Montoya's future team has been struggling this season

The Williams driver has been at the centre of increasing speculation that he is trying to extract himself from the contract he signed with McLaren.

McLaren have made a dismal start to 2004, taking just five points from the first six races of the season.

But, speaking on a visit to Bulgaria for Williams, Montoya said: "I'll be a racer for McLaren-Mercedes (in 2005). That's for sure."
