Daniil, welcome and happy birthday for yesterday. It is of course a home race for you but that means an awful lot of commitments. Were you able to even enjoy your birthday?

Daniil Kvyat: Yeah, I was. Obviously you have to expect that you have a bit more things to do at your home race. I think it's a privilege for any driver to have a home race and it's a privilege for me. Of course I was in Moscow a few days earlier for a few events and here also yesterday was quite a busy working day for me to be honest, but it was still enjoyable, I was surrounded by nice people and it was all quite nice. I learned how to do curling, so now another sport on top.

This is the fourth year of the Russian Grand Prix in Sochi? How do you feel the popularity of the event has grown during that time?
DK: You know, to be honest I think that since year one there has been quite full grandstands, so it's been quite good already. Not too much to add since the first year, so it's a point to maintain this. We will see this year but I am expecting to see quite a lot of people here on Sunday and the weather is nice so everyone should enjoy. Hopefully the race is going to be interesting and that's it really. I am pleased to see this.

Let's talk about your on track performances: you scored points in Australia, but you haven't had much luck since then. How do you assess your season so far?
DK: First of all, it was already a privilege to finish the race in Australia, for me. It was a good start but for me it was more important to know that we have the pace to do good results. As you said, China and Bahrain were a bit not our kind of weekends. More important for us to know that we have a package to do things well. The team is operating extremely well this year from the operational side of the things - very professional, especially considering how tight the midfield is, every little thing makes a difference for us. It's actually quite interesting. Very interesting every qualifying session. You are putting yourself at the limit and the same in the races. It's very interesting to be there.

Tell us a little bit more about this year's car. What are its strengths and weaknesses?
DK: Our car in particular, I would say, is quite universal. It's been a similar kind of performance in every track so far - Australia, China, Bahrain, it's always similar, fighting for points, Q3s. Like I said before, you have to put everything well together and the difference between the fourth best team and the seventh best team is very, very narrow.

Thank you for that and good luck for the weekend. If we come on to Valtteri now. Valtteri, you made a step forward in qualifying last time out but to use your own words the race was a disappointment. Given you have a record here in Sochi, are you confident that this is the place to make that final step?
Valtteri Bottas: Yeah, I think definitely it has been getter better in each qualifying of the year and feeling that I can definitely extract more and more out of the car and had a nice lap in Bahrain on Saturday but, yeah, it is Sunday that counts and to be honest I think the first race of the year in Melbourne, as a Sunday, was the best one for me. It was the most trouble-free race for me. Been having quite a few difficulties in China and Bahrain - technically, with different kinds of things in the race. So hoping for a good one here. We have a strong package and obviously the fight with Ferrari is extremely close and every single bit is going to count, so yeah, just hoping for a good weekend.

You just referenced the technical problems you had in Bahrain. But you then went and did 143 laps in testing after the grand prix, during which you said you'd learned a few tricks. I just wondered what those tricks might be?
VB: Like I said, it's all about fine details with the fight between us and Ferrari and obviously it's very close between team-mates as well, so every single bit helps. It was quite critical in Bahrain with the tyres, in terms of keeping them in the right window and with the tyre pressure issues we had it made it even more tricky. Bahrain testing allowed me to try a bit of different things for that really - how to manage the tyres. In terms of race pace and temperatures and pressure and everything we could experience a lot of different things. We found small things as a team, but small things are going to help. It is completely different conditions here in Russia, different tarmac, different temperatures, so we are facing different challenges here.

Just finally, you've now completed your first 100 days as a Mercedes driver. How would you sum it up, how's it gone?
VB: Busy! Especially since January when everything was signed and announced it has been a busy time. But I have to say these 100 days, I've never in my life learned so much in that short period of time. I feel like I've been developing well. I've managed to get really into the team, I feel completely part of the team and I feel like I'm in a very good place. The team is really helping me with that. I've learned massively but that's going to continue.

Thanks for that. Romain, first points of the year last time out in Bahrain. So, how confident are you of another good result here? Do you even know yet how good this year's car is?
Romain Grosjean: It's a shame we're not at the next press conference - I always said I was going to wait four grands prix to see what the car was capable of doing. We've had three different track right now and Sochi is the fourth one - very smooth tarmac and last year we had ups and down. This year it looks like the car has been strong everywhere. Only first point in Bahrain but I reckon we should have scored points in Melbourne and in China, we had a little bit of bad luck. So far, so good. Just waiting that grand prix to see how the car is going around and if we can get all we want and if we can get the tyres to work properly and so on. If that's the case then we know we should be pretty good everywhere and then it's just going to be down to development.

Can I ask you about the test last week in Bahrain. You tested Carbone Industrie brakes. How did they compare with the Brembos you have been racing? Are they the solution to the braking problems you've had for pretty much the last 18 months?
RG: To be fair to Brembo, the last update in brakes we had that arrived in China were much better. It took a long time to get them. So then I was not screaming to change to Carbone Industrie but it was in the pipeline, so we tried them, and both drivers were pretty pleased with them. We felt like we had more control under braking. I'm very sensitive to my left pedal, so I really need to get good brakes to get good confidence and push the car to its maximum limit. So we are going to run them here. There is still a little bit of work we need to be doing around the mapping and finding the solution around those brakes but I think yeah, definitely it's going to help me a little bit to find the last few hundredths.

So just to clarify you are going to run the Carbone Industrie here in Russia?
RG: Yes.

Questions From The Floor

(Luis Vasconcelos - Formula Press) Valtteri, as you mentioned, your qualifying has been getting better and better but your race pace has not been what you expected. But it's especially in the first half of the races that you seem to be struggling more, when the car is on full tanks. Have you find out why is that and in testing in Bahrain did you find a remedy for that?
VB: Yes, so like I said, I think Australia was the only race when everything was actually working as it should in the car. There was a small mechanical issue in China which was affecting the balance of the car quite a lot and it made the race overall quite tricky. Plus, I didn't maybe do the best job with the softer compound in the beginning. And in Bahrain my race was compromised with the issue we had with the generator on the grid, meaning the tyre pressures were way too high and the first stint was very poor. We were hoping the second stint would be better, so we fitted another set of supersofts. It was better, but we didn't manage to be really in the window with the supersoft. At the same time Lewis changed to softs and that was why there was a massive difference with the pace and then we were on different strategy, different points of having the stops and to be honest it made me look really bad in the race and slow, but for sure we had some issues as well. But I feel that with a normal, trouble-free race the good results will come and we can have a strong result with both cars, definitely.

(Kiril Zaytsev - 66.ru) A question for Daniil Kvyat. Dany, if Max Verstappen strikes somebody off the start, will Dr Marko replace him by you?
DK: It's a question for Dr Marko, not for me.

(Simon Lazenby - Sky Sports) A question for Valtteri. Valtteri, it looks like it's going to be tight, obviously, between yourselves and Ferrari this year. With that in mind, have you had a conversation with Toto or any of the management about when one of you or Lewis might become the number one or number two driver?
VB: No, we have not had the conversation because I don't think there is any need to. This team never really has had number one or number two drivers and is not planning to. It's always trying to give and equal chance for both drivers. But what is different this year is, for the team the last three years, the gap to the second quickest team has been bigger. So maybe every single detail - letting the drivers race hard, or one being stuck behind the other at times hasn't cost anything. But I do understand the fact that this year it can cost points. If for any reason, like for me In Bahrain, the pace of the other car is not good then the team needs to think and be clever and not to lose any points. We've only had three races this year and I feel all my good results are still on the way, so at least I am not thinking about anything like that and I'm sure also for the team there's no need to.

(Dieter Rencken - Racing Lines) Based on the latest information from the FIA, it appears as though the cockpit Shield has received the nod for 2018 over the Halo. What do you think about the Shield and which one would you prefer the Shield or the Halo?
RG: Can we choose nothing. I haven't been a big fan of the Halo and I'm not a huge fan of the Shield either. I don't want to stop the safety. I think safety in Formula One has to be the number one priority but I don't want to change what I've known as Formula One since ever and the next step is to put a closed canopy on top of the helmet and I don't want to see Formula One being closed cars.

DK: I agree with Romain, you know, I think it's enough for now the way Formula One should look should remain the same. I think we have enough protection so far. Of course if there are good ideas they should be considered but so far I am quite against it to be honest, both of those options.

VB: I don't mind the Shield. I think it looks quite OK. I think it's definitely a good step compared to the Halo. That's my personal view, how it looks, so I don't mind that. I think the safety aspect is always important. It's always important to keep things improving, developing - safety always needs to be improved. So I wouldn't mind trying out the Shield, seeing how is the visibility and if there are any other issues with that. But I think in terms of safety it would be a good step compared to what we have now.

(Marco Mensurati - La Repubblica) A question for Valtteri, again about his first 100 days in Mercedes. When you signed, did you expect that it would be so hard, so difficult and which is so far in your opinion the biggest mistake you made?
VB: I can answer the second question first: spinning behind the safety car in China, I think that's the biggest mistake I've done, it could be through my career most likely...

RG: I've done it, no worries...

VB: Yeah? Hopefully the last one

Daniil, have you done it?
DK: No, but on the out lap...

Everybody's done it. Back to you Valtteri.
VB: For sure I always knew it was going to be a big challenge: a late change of team in mid-January, going up against Lewis, probably one of the quickest drivers ever, so I always knew the facts of changing team. I have to say there was quite a bit more stuff to really get good at, in terms of really learning how the team operates and how the team is setting up the cars - different kind of tools to what I'm used to, and a different way of thinking in some ways. Getting to understand that 100% there has been quite a bit of work. Obviously all kinds of other things: how the car behaves mechanically, new tyres, new cars, which is the same for everyone. So I wouldn't say I underestimated the change, but it's definitely been a challenge as I expected but like I say, I'm getting there. My goal was to be able to extract everything there is in the car in the first race, first qualifying. I don't feel like that I maybe achieved. But also allowed myself some time, not to put too much pressure. I knew that it's not going to be easy. But like I said, feeling very comfortable now, good with the car, good with the team. Overall a good feeling, just happy to continue and get some results.
