Jose Mourinho's trusted lieutenant Baltemar Brito last night admitted that the Chelsea manager was disillusioned with recent events at Stamford Bridge and said that he would not attend tonight's Champions League quarter-final with Bayern Munich.

It is the first time that anyone from Mourinho's management team has confirmed his disaffection with Chelsea since reports emerged in Portugal last Friday that he was contemplating quitting the club in the close season.

That threat has now been withdrawn, at least until the next time Mourinho is upset by the Chelsea hierarchy, leaving a fragile peace between club and manager.

"When he comes to a new club or starts a new job he gives 100 per cent to what he's doing. He expects 100 per cent back," said Brito, Mourinho's Brazilian assistant manager. "Whether he has that is something you can ask Jose but I acknowledge that perhaps he felt that he didn't get 100 per cent back. (Nonetheless) Jose is happy."

It was the first press conference in which Brito has represented his club and the absence of Steve Clarke, the joint assistant manager, was a public reminder of the Scot's role in Mourinho having received a two-match touchline suspension.

The Portuguese acted on the testimony of Clarke and the security officer Les Miles in making his allegations of an improper conversation between the referee Anders Frisk and the Barcelona coach Frank Rijkaard during the two clubs' second-round tie at Camp Nou.

That led to Uefa disrepute charges and the subsequent sanctions but Chelsea insist there is no split in the management team and Clarke will have joint responsibility for the side in tonight's match.

Mourinho's ban prevents him from partaking in any touchline, dressingroom or press-conference activities during the two encounters with the four-time European champions, however, although he is permitted to take a seat in the stands, Mourinho has decided against even travelling to Stamford Bridge. He is likely to watch the match from his central London home.

"Jose will be in a private place on his own," said Brito. "It will be a very peaceful place to watch the game with no contact with any member of his staff."

Uefa is keen to take Brito at his word. Though the imposition of the touchline ban includes the proscription of any form of contact with his dressingroom, there will be no proactive attempt to enforce that element of the punishment.

Had Mourinho chosen to attend the match, a Uefa official would have sat by his side to ensure the European governing body's sanctions are observed but that will not be possible if he remains in his own home.

"It is not a question for us to control Jose," said the Uefa media delegate Fritz Ahlstrom. "It would not be fair. We have taken a decision whether they like it or not. We presume that it will be respected by Jose and Chelsea. It's a not a question of shadowing anybody or policing anyone.

"I think he will obey the decision. But I never expect anything, I don't take anything for granted, because then I never get disappointed."
