'We now know what the rules are,' said Montoya who finished fifth after being forced into a first lap pit-stop for a new front wing after the collision. 'I gave him room at the first two corners then he cut across me. Next time I will just do the same as him.' Schumacher had insisted after colliding with Montoya for the second successive race that he was not at fault and refused to respond to the South American's claim that he was an unfair driver. Britain's David Coulthard admitted he will struggle to fight Ferrari and Williams this year, despite making his first visit to the podium. The McLaren driver was forced to battle with the Renault of Jenson Button before finishing third.
