West Ham boss Sam Allardyce thinks Jose Mourinho is an even better manager now than when he last worked in the Premier League.
Mourinho led Chelsea to five major domestic trophies in just three seasons before leaving in 2007 and is expected to return to Stamford Bridge this summer, his departure from Real Madrid having been confirmed on Monday.
And Allardyce says Mourinho will have benefited from his stints with Real and Inter Milan, who he led to a treble in 2010 before heading to Spain.
Asked how he thought Mourinho would do if he returned to England, Allardyce said: "I suppose it depends on whether he can recapture what he did when he first moved to Chelsea.
"Looking at his experience since those days, he should be better than he was when he left.
"I think that, with his spell in Italy and his spell in Spain, he will have matured and learnt an awful lot from that time.
"I suppose when he comes back to Chelsea he'll use that experience and probably try to be better than he was before he left."
Allardyce hopes Mourinho will indeed be working in the capital once again and is eager to lock horns with the Portuguese boss.
"I think it will be great to have him back," he said.
"He had a very good spell last time. I know it didn't finish so well in the end at Chelsea with (owner) Roman Abramovich but obviously they've repaired that damage and it sounds like he's looking forward to coming back to England.
"We'll be glad to see him and obviously pit our wits against him again."
England manager Roy Hodgson agrees that Mourinho will be warmly welcomed back into English football.
"He's very popular and did a wonderful job last time he was here," said Hodgson.
"I'm sure that the people, especially the media people, will be very pleased to see him and, whichever club happens to get him as a manager, will be very glad to have him there."
