Hiddink admits he is still feeling the "anger and injustice" of Chelsea's controversial semi-final exit at the hands of Barcelona, who face holders Manchester United in Rome on Wednesday night.

The Dutchman made his comments after Europe's governing body charged Chelsea over the improper conduct of their players and the throwing of missiles by fans in the return leg at Stamford Bridge.

Ivorian striker Didier Drogba and full-back Jose Bosingwa were also accused of insulting the referee and making offensive remarks.

Drogba's foul-mouthed TV rant and furious confrontation with Norwegian referee Tom Henning Ovrebo at the end of the game could now land him a five-match European ban.

Ovrebo rejected four penalty appeals as the Blues crashed out on away goals after a 1-1 draw and Chelsea's players protested angrily when the official brought the game to its conclusion.

The club, if found guilty, may also be slapped with a massive fine or, in the worst-case scenario, be ordered to play some European games behind closed doors. However, it is unlikely they will be banned from next season's competition.

But Hiddink, taking questions from fans on Chelsea TV last night, rejected a conspiracy theory aimed at preventing a repeat of last season's final between the Blues and United.

"It is difficult to talk about conspiracy if you have no proof," said Hiddink. "I am rather human as well and I think UEFA, they will not say it, were very happy there was not an all-England final for the second consecutive time.

"First of all we should have scored more goals in the home game but besides that I feel the anger and the injustice.

"This was not an inexperienced referee. He had some problems in the past but he was not inexperienced. I do not know what happened that night.

"I think he had a total blackout that evening. It was not his first big game but it was amazing how he did not react."

Hiddink also revealed he has rejected invitations to be a TV pundit at the final between United and Barcelona next Wednesday because of the manner of their exit.

"It is still fresh, to be honest," he added. "Next week is the final and I will watch it. Last year I was in Moscow doing some comments for TV and I always did the same in previous years.

"This year they asked me again but I am not going. I don't have the right feeling to go and sit there and not think about what has gone wrong."
