Dennis decides not to play 'blame game'.

A frustrated McLaren-Mercedes were keeping blame to a minimum after both Kimi Raikkonen and Juan Pablo Montoya emerged the highest-profile victims of the second corner crash in an incident that initially appeared to lay blame at the Colombian's door.

With the tight second half of the first corner chicane often causing some problems in previous years, Montoya seemed to run into the back of Raikkonen after the Finn was forced to break early when he was squeezed by Jenson Button.

Raikkonen's ensuing spin pushed Button into Heidfeld, flipping the BMW into the air, while Scott Speed also became tangled up with the McLaren and causing all five drivers to retire.

The incident has left McLaren-Mercedes now someway behind their Ferrari and Renault rivals, who got both of their cars to the finish, in the constructors' standings, although Ron Dennis was remaining coy over who was to blame for the clash, even if he did point out Heidfeld as a possible culprit.

"We have looked at our data and the footage from various cameras and it's clear that as is often the case with accidents several things happened in close sequence," the team principal said. "Heidfeld heavily squeezed Button, who squeezed Juan Pablo. Prior to those cars touching Juan Pablo ran into the back of Kimi who was making very effort to keep out of trouble.

"Inevitably the team feels intense frustration and disappointment when its cars are eliminated as a result of touching each other. However this was a racing incident and should be treated as such."

Raikkonen was also in no mood to be apportioning blame, turning his attention instead of the coming races having now slipped behind Giancarlo Fisichella in the drivers' standings.

"I made a really good start and was quick off the line. However things got messy at the second corner and Juan Pablo hit me from behind and that was the end of the race. There is no point in blaming anyone as these sort of things happen in racing and especially when you are not at the front. As a team we will now get over the disappointment of today's result and focus on the next race."

Montoya meanwhile was upset by the incident but insisted that he had been squeezed into Raikkonen by Button's Honda.

"When you start so far back you have to race hard to make up places. Unfortunately it was pretty tight at the start and as everybody braked for the second corner I was being squeezed by one of the Hondas and regrettably I hit Kimi. I'm obviously really upset for the team who have worked so hard the whole weekend as having both cars out on the opening lap is disastrous."
