Nov.26 (GMM) Kazuki Nakajima may have entered formula one with Williams too soon, according to David Coulthard.

Coulthard, the Scottish veteran of 229 grands prix, also made his grand prix debut for the Grove based team, in 1994, but he is critical of the Japanese rookie following his maiden outing in Brazil last month.

Nakajima, who is 22, will graduate full time from GP2 to the pinnacle of motor sport in 2008.

"He passed me on the outside into turn one (at Interlagos), which was fair enough, but there was no need for him to cut across the front of me afterwards," Coulthard wrote in his column for ITV.

The 36-year-old spun as a result of the clash and reported damaged suspension for the rest of the race.

Nakajima, who also hospitalised some of his pit crew after hitting them in Brazil, said of the Coulthard clash: "I was ahead, so I think it wasn't my fault."

Coulthard insists that his criticism of the rookie is not sour grapes about the "old boy getting overtaken by the new guy".

"Driving standards in GP2 are generally pretty wild. My teammate Mark Webber said recently, 'F1 is not a finishing school' and I totally agree," he added.
