Sep.12 (GMM) David Coulthard has rubbished rumours that Sunday's Italian grand prix at Monza could be his last ever formula one race.

It has been suggested that, as the 37-year-old is due to retire anyway, Red Bull might ask him to step aside early so that Sebastian Vettel can switch camps in preparation for 2009.

Vettel's subsequent vacancy of his Toro Rosso race seat would also give the junior team a chance to evaluate at actual grands prix his replacement for next year.

The speculation then stepped up a gear at Monza on Thursday, when Red Bull opened a photographic tribute to Coulthard's long F1 career in the team motor home.

"This is not my last grand prix," the Scot is quoted as saying on Friday by Formule 1 Race Report. "I am finishing the season, no matter what some of you want," Coulthard joked.

"Only after Brazil is it really going to be all over for me."
