With much speculation about his future, Valtteri Bottas has conceded that winning a Championship with Williams would be “very difficult".
Bottas is one of a number of drivers who Ferrari might consider as a replacement for Kimi Raikkonen should they not renew his contract for 2016. Bottas' agent has previously admitted that he only has an option with the Grove squad for the 2016 season.
The Finn's position comes at a time when Williams are on par, if not slightly quicker than Ferrari. At Silverstone, they were clearly the faster outfit, but it remains to be seen if this pace can be maintained at other tracks on the calendar. Ferrari have acknowledged that Silverstone did not suit the SF15-T at all.
Speaking to F1i, Bottas believed that although Williams had made some strides, Ferrari remained slightly ahead while Mercedes continued to dominate. This is why he believes it would be very difficult, but not impossible for a Williams driver to become world champion.
"Williams has been many times World Champion, I've always said there's no reason why they couldn't do it again, but the fact is at the moment it's very difficult," he said.
"There are teams with much bigger budgets as everyone knows. Mercedes is dominating, now Ferrari are a bit ahead of us at the moment so it's not easy at the moment, but I'm not going to say it's impossible."
Bottas would not be drawn into speculation about his future which he added, was handled by his management team. For the time, Bottas stressed that he was focussed on performing at his best.
"In Formula One things can change quickly and if there are opportunities sometimes maybe you need to go for it, but for sure you also need to be in the right place at the right time," he said.
"Wherever you are, whether you've been somewhere for a short time or a long time, for me it's always going to be the case that I'm going to do everything I can for the team and improve the car.
"So for me it's no different if I'm somewhere for three years, ten years or one year, I'm still going to do everything I can to help the team and get the best result."
