Juan Pablo Montoya believes he is the main challenger to Michael Schumacher, despite the current champion thinking his brother Ralf is the one who poses the threat. Montoya and Michael have already been fighting it out on track this season with some daring overtaking moves and a clash of heads at the first corner of the Malaysian Grand Prix. With twelve championship points to the German's fourteen, Montoya is currently second in the standings.

"I don't accept what he has to say," he said, regarding Michael believing Ralf is his main rival. "I am running second in the championship. Plus we look to be stronger to McLaren. You could say that at the moment I look like the best contender he's got. But it might change as the year goes on. From his position he might say his brother is his biggest rival. If I was him I would say that."

This weekend's Brazilian Grand Prix is the scene where last year Montoya overtook Michael in what was voted the move of the year by many. Looking good to win the race, the Colombian was denied the victory by Arrows' Jos Verstappen hitting him from behind after he had moved over to let Montoya past. Ralf Schumacher is currently just two points behind his Williams team mate in the standings and Michael has stated on more than one occasion that he believes his brother is more of a threat than Montoya.
