The whole thing is fabulously unlikely, Formula One chicanery at its most melodramatic. The facts are Ralf Schumacher is contracted until the end of next season and Montoya, who took Button's seat, is presently in mid-negotiation for a two-year contract. Confirmation that he will stay is expected next month. Funnily enough, though, Button has added a handy caveat to his startling claims, insisting he is "not convinced that going back to Williams would be in my best interests".
