Fulham manager Martin Jol has challenged Zdenek Grygera to prove he’s worth a new contract over the course of the season.

The Czech defender only signed a one-year deal when he joined from Juventus on a free transfer on the final day of the summer transfer window, although it does have an option for another year. Jol wants the versatile defender to earn his contract extension by continuing his fine recent form.

Grygera has been good from the first game. We have agreements with him, and if he plays a certain role and does well we’ll sit down [and talk]. However, the risk is he could go to another club as well.
