One driver been looked at by the WilliamsF1 team is current test driver Antonio Pizzonia. Antonio filled in for an injured Ralf Schumacher and performed well for the team,, scoring points in the four races he entered.

In an interview with the AtlasF1 web site team boss Frank Williams spoke of how the Brazilian would be on their list of drivers to replace Button if he could not join the team.

In the interview Williams said: "Certainly he [Pizzonia] would be on our list. Since December 2001 he's done tens of thousands of kilometres of testing, he has thereby accumulated a substantial knowledge of what makes racing cars go tick and which are the quick ways around Grand Prix circuits, and he has learnt what not to do. That is not to say he hasn't got much more to learn, but I think if he is in a good team, if he finds himself on a good team he could be capable of winning races in due course."

Antonio spoke of his desire to join the WilliamsF1 team on a full time basis but if this did not come about would be happy to continue as a test driver.

Pizzonia said: "I really want to race. You never know, if Jenson doesn't end up coming back to Williams then maybe I'll get a chance to race for them again. Unfortunately there's not many seats in the top teams anymore, so if I don't race for Williams I'll test for them, I've got that contract already.

"In a way I wish that the races I had were a bit earlier in the season, because maybe I could have had more chances at a race seat with the other teams, or maybe even with Williams as well."
