The sky is the limit for Chelsea coach Jose Mourinho, his father claimed, after the Portuguese manager was voted the best football coach in the world in 2004 by the International Football Federation of History and Statistics.

"I now think anything is possible in his career as he is getting better and better," Felix Mourinho told Portuguese state radio RDP.

"As you can imagine I feel really proud and really happy. But I have to say he works very hard to achieve what he does. He works a lot, he is very dedicated, he lives for what he does," he added.

Mourinho beat Arsenal's Arsene Wenger with a 186-point advantage in the annual ranking, while Monaco's Didier Deschamps finished in third position.

Barcelona coach Frank Rijkaard, whose team dominates Spain's Primera Liga, came fourth while Liverpool boss Rafael Benitez finished in fifth position.

Mourinho, who joined Chelsea in June 2004 from FC Porto on a four-year contract, has guided the London-based team to a 10-point lead at the top of the English Premiership.

During his last season at FC Porto, Mourinho led the club to the European Champions League, UEFA Cup and Portuguese league titles.
