The Romanian failed a drug test and admitted taking cocaine but Mourinho conceded it was impossible to control what players did once they had left the confines of the training ground.

But he said that the Premiership giants were doing all they could to ensure their current academy youngsters know all about the possible pitfalls that lie in wait.

"A professional player has to be aware of what he can do and what he should do," said Mourinho who has been hit with the scandal as he prepares for Wednesday's Champions League clash against CSKA Moscow here.

"That's professional education. I don't know what all of them are doing outside of their professional life - it's impossible to control it. Impossible.

"But when I see the enthusiasm and commitment of the players on the training ground I only believe they are top players who are giving everything.

"The director of our academy is working very hard in passing this information to the kids. We want to teach our kids how to behave as professionals in the future. We have a rule book and that means a lot."

Mourinho added that he had not spoken to Mutu and would not comment on why he was not available for Wednesday's game.

"I don't know when he will be fit. I don't speak with him. I do not want to concentrate on players who are not in the squad," said the coach.

"He has not been available since the previous Monday when he could not work with the team.

"I received written information from my medical department saying he was not available to train with my group. When they don't train with my group, they don't play.

"I have 19 players for Tuesday and I only need 18, so one of them will have to sit in the stand."

However, when quizzed as to why Mutu played for Romania against the Czech Republic in the World Cup qualifier last week, Mourinho said the question should be directed to the Romanian team doctors.

Mutu has admitted to testing positive for cocaine and will not request that a 'B' sample be analysed according to players' union chief Gordon Taylor.

The Chelsea striker met with representatives of the Professional Footballers' Association (PFA) and will not insist on counter-analysis of the original test which proved positive for cocaine.

"He will not be going ahead with the second test. He has tested positive for cocaine," Taylor told the Press Association.

Taylor expects there to be PFA representation at the hearing while Mutu's advisors should also be free to attend before an FA commission, who must decide the Romanian star's fate.

The player could be suspended for up to two years but he can expect a lighter penalty, particularly in light of his early admission and acceptance of the original test result.

Mutu's representative Gheorghe Popescu revealed the player has been "destroyed" but hopes to escape with a six-month suspension by coming clean.

Former Romania midfielder Popescu, now one of Mutu's agents, advised the player not to seek counter-analysis of his sample.

"Mutu is destroyed. I told him to assume full responsibility for his actions but he seemed not to understand," said the former Tottenham player.

Mutu, signed from Parma for 15.8million pounds last year, now faces having his lucrative 60,000 pounds a week contract ripped up by Chelsea.

Mutu fell out with Mourinho over his decision to defy the club and play for Romania in their World Cup qualifier against the Czech Republic last week.

The striker played despite a knee problem and Mourinho fined him two weeks' wages on his return to England.

He has now been told to stay away from the club's training ground.

The club and the Football Association have yet to make any comment.
