This week, the Manor Marussia F1 Team are in Sochi for Round 15 of the FIA Formula 1 World Championship, the 2015 Formula 1 Russian Grand Prix. The Sochi Autodrom is an extremely technical circuit, one that many struggled to get to grips with last year when the track made its debut on the calendar.

Will Stevens: "I'm really looking forward to the challenge of Sochi. I was here last year in my role as Reserve Driver, so I walked the track and observed the task of getting to grips with it from afar. It's quite useful having two different drivers as a benchmark this past few races, and of course it is Roberto back in the other seat for this race, rather than Alex. This is a really technical track and I can't wait to get my first experience of it on Friday."

Roberto Merhi: "I can't wait to be back in the car in Sochi this weekend. It's the first time I have raced here, but last year I took part in the FP1 session, so I have some understanding of the circuit characteristics and this will be helpful for me after a couple of races out of the car. I've continued to work very closely with the team during track sessions and engineering meetings, so I have a very good appreciation of the work we have completed and I'm eager to get stuck into the programme and to make the most of my two races, in Sochi and Abu Dhabi."

John Booth, Team Principal: "The debut race in Sochi last year was something of a voyage into the unknown for all of the teams. For us, it was an even greater challenge, given our difficult circumstances. For me personally, this will be my first visit, so, in many ways, we approach the race afresh this weekend. The lap here is very long, second only to Spa and Silverstone, and it is a very technical layout with plenty of hard braking zones leading into slow corners. It will be good to have Roberto back in the car here for the first of his two remaining races with us, and I'm sure Will is going to be pushing hard to reverse the disappointments of the last couple of races."
