Tottenham coach Juande Ramos says Jermaine Jenas can be a "star player".

Jenas has been transformed under Ramos and England boss Fabio Capello preferred the midfielder to Manchester United's Michael Carrick when he trimmed his first England squad.

"We have worked on his mental and physical preparation and helped him believe in his own potential," said Ramos. "He has made a tremendous effort to get there and he deserves it.

"He has a lot of capability and there is still a great margin of improvement with him. We just have to see whether he can keep evolving or not. If he does, he will be a star player."
