They are accused for making “false, wrong and unfounded” allegations that Barcelona boss Frank Rijkaard spoke with referee Anders Frisk in the referee’s dressing room at half-time during the match in the Nou Camp last month.

UEFA say Chelsea’s claims created “a poisoned and negative ambience” in an attempt to influence the second leg, and Chelsea could face the ultimate sanction of disqualification from the Champions League when their case is heard on March 31.

But Chelsea are thought to have been taken aback by the charges and by the tone of UEFA’s criticism, and Mourinho told Portuguese television last night: “I have the expectation of complete dismissal, complete dismissal.”

Mourinho added that he would not change his behaviour.

“I have always been this way. Sincerely, I don’t want to change and I want to finish up my career 12, 13 years from now at most, I want to finish it up this way,” he said.

“That is, to be loved by my own. And right now I am loved by the Chelsea fans and I don’t worry hardly at all about other club’s supporters. That’s the way I am.”

Barcelona won the clash at the Nou Camp 2-1, but Chelsea won the second leg 4-2 to advance to the quarter-finals.

Frisk subsequently announced his retirement following death threats to him and his family.

Chelsea’s case will be heard by UEFA’s control and disciplinary body on Thursday week in Nyon, Switzerland.

Mourinho insists he will have plenty to say about the club’s run-in with UEFA once the case is settled.

“I think a lot, but at this moment I can’t really talk about it,” said Mourinho.

“In the future I’ll talk more. Once the case has been closed and the lawyers have opened the door for me to speak, I will speak out a lot more, but now I have to wait for the process to finish.”

Mourinho feels misunderstood and believes his actions are being seen, unfairly, in a negative light.

During the Carling Cup final at the Millennium Stadium, Mourinho was asked to leave the pitchside after raising his finger to his lips when Steven Gerrard’s late own goal equaliser enabled Chelsea to go on and secure an extra-time victory against Liverpool.

The Chelsea boss apologised but insisted his gesture was aimed at media critics, who were on the other side of the stadium, rather than the thousands of Liverpool fans, who were sitting just behind him.

“I’m spontaneous,” he said. “When I say something it is not in order to provoke. Strangely enough, the same gesture that I had for the British versus Liverpool a few days ago, I saw [Inter Milan striker] Adriano do the same, presumably criticising because his team is not scoring.

“This gesture happens often, but everything that I do is seen and analysed in a negative way.”
