Adrian Sutil says he has nothing to prove as hunt for 2012 Formula 1 seat continues

Despite a strong second half to the campaign, and another impressive performance so far at the Brazilian Grand Prix, Sutil does not yet have a confirmed place on the grid for 2012.

He is still awaiting a final decision from Force India about its plans for next year, but has also been strongly linked with drives at both Williams and Renault.

Although there is no certainty yet about what he will do, Sutil says he is not worried about his future - especially because his strong performances have put him in good stead to land a decent seat.

"From my point I have shown everyone was I am able to - more I cannot do," he said when asked by AUTOSPORT about his future situation.

The German is weighing up options on the grid, and has admitted for the first time that Force India is not necessarily his main target - with speculation continuing to suggest that the outfit will take Paul di Resta and Nico Hulkenberg.

"I have no first choice," he explained. "I am very loyal to this team and Vijay [Mallya, team principal] was loyal to me, so that is why whatever I do I am honest to him. At the same time I hope he is honest to me.

"That is why we have to wait a little bit. I like this team, I feel very comfortable and I think in the last years we have improved so much. It makes me proud because we have worked together and now where we are is impressive, so I am fine to do another season here, absolutely."

When asked if he was frustrated that on the back of his best season in F1 he still had not a certain future, Sutil said: "You can probably not be 100 per cent, but what is 100 per cent in this sport?

"Even with a contract, they can kick you out and pay you a lot of money, and then you have no chance. So you have to perform every race, and you have to perform as if it is your last race.

"Some races you are doing not good and then you are nowhere, then you do some good races and you are up on the top again. It is a very fast business here, I know how it is. It is always nice to have a contract but it is never 100 per cent."
