Sep.21 (GMM) Adrian Sutil has admitted that "several" other formula one teams have expressed interest in signing him for the 2008 season.

But the impressive German rookie said actually driving for one of them, amid speculation of links with teams like Williams and Toyota, would involve the consent of Colin Kolles -- and someone willing to buy out his solid Spyker contract.

"There have been some talks," Sutil said in an interview with Auto Motor und Sport, "and there has been a lot of other feedback from some of the other teams.

"Several have shown interest in me: the only question is, will someone agree? And then will it be something that I will want?

"Naturally no-one has said simply: drive for us. Each team has enquired carefully but there have been various discussions. But my contract with Spyker also applies to 2008.

"So if a change is possible for me into a top team, then also Colin Kolles must agree.

"We have contacts with three teams. I cannot say who they are -- we have an agreement with Spyker, so everything we do is in interaction with them.

"Kolles gave me this chance and so I will behave loyally to Spyker," Sutil said.
