Max Chilton says he feels he has done enough this season to earn a second year in Formula One in 2014.
The Briton has taking the flag in every race so far with Marussia and was able to outqualify team-mate Jules Bianchi
at Suzuka at the weekend.
While Bianchi has already been confirmed in his seat for 2014, Chilton's future has still to be announced but he said he felt he had done enough this season to show he is worthy of a second year,
"I feel I'm showing not just the team, but everyone on the whole, I deserve a seat for next year," he told the Press Association
. "Everyone gets judged, so you have to prove yourself, which is hard for rookies these days because there is so little testing, which means it's going to take part of the season to get up to speed.
"I admit, at times, I haven't got things right, like at Silverstone and Germany, but on the whole it has been pretty good, and since the August break especially I couldn't have done much more.
"I've been really happy with my performance, as have the team, and I've been really happy with them, so it's going really well."
While he feels he has already shown he deserves a seat however, Chilton admitted he had to keep performing on track to ensure the team didn't decide to look elsewhere.
"I've proven I've got the pace and consistency, as I'm now the only driver to have finished every race," he said. "In Formula One, like in any sport, it's the whole package. Sometimes it's not always about ultimate pace, you need to prove you can bring the car home in the races. If you're not in it, you can't win it.
"The last five races have been really encouraging, and to do what I did in qualifying [in Japan] was a step in the right direction."
