Jermaine Pennant will have to tread carefully in the coming months if he wants to stay with Liverpool.

The News of the World says Pennant is on a final warning at Anfield.

The winger, sent off in Porto, looked to be heading for the exit door last season but rescued his career with a string of impressive performances.

But Rafa Benitez was furious with his needless dismissal against Porto and read him the riot act.

And Pennant will now have to be a model of discipline if he is to avoid being offloaded in the January transfer window.
