As in previous years, Adrian Sutil has indicated he is potentially on the market to switch teams.

The 27-year-old German made his grand prix debut with Spyker in 2007, staying with the same Silverstone based outfit when it became Force India.

Sutil has often indicated he would change to a bigger team, but he told Germany's Sport Bild that he is happy with Force India's recent rate of progress.

"As long as every year there are steps being made, I am very satisfied," he is quoted by the Munich newspaper TZ.

But Sutil admitted he is keeping an eye on the potential seat movements at a couple of top teams.

"We have to see how long Michael Schumacher wants to go on. And also what happens at Red Bull," he admitted.
