"I know that there are stories and speculation that swirl around, and I guess that's F1 and I think we're content to get on with the job quietly," he said, "As I said earlier, I think we're very focused on trying to do a good job here.
"I think it seems [to have taken] a long time because of the speculation that people have made, but when you sit down and seriously put your mind to entering into a new contract it doesn't take too long. I think it's a question of priorities and other things we've been doing. I'm sure he will want more money and I'm sure we will want to pay less - that's how business normally works.
"As I said earlier, it's not a question of putting on a brave face, it's a question of focusing on doing our job, and we're concentrating on this year's championship. I think speculation on next year is something that we don't need to entertain or respond to so we're focusing on the here and now. We might wait until [the end of the season], you never know."
