"For the future, there are drivers like (Briton Lewis) Hamilton, or (Finland's Heikki) Kovalainen who could possibly win championships," he added.

Fisichella's contract expires at the end of the season while test driver Kovalainen could be promoted to a full race drive.

Hamilton, a winner in all the junior series he has entered, is backed by McLaren and looks likely to join that team in some role next year.
