CHELSEA are set to pay a heavy price for their controversial Champions League semi-final exit to Barcelona after UEFA hit the club and two of its top stars with disciplinary charges.

Chelsea were charged with the improper conduct of their players and the throwing of missiles by fans, while Ivorian striker Didier Drogba and fullback Jose Bosingwa were 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 earn him a lengthy 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 given 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.

A statement from UEFA said: ‘‘UEFA has initiated disciplinary proceedings against Chelsea FC, Didier Drogba and Jose Bosingwa in relation to incidents following the UEFA Champions League semi-final second leg against FC Barcelona at Stamford Bridge.

‘‘The club are charged with the improper conduct of their players and the throwing of missiles by their supporters, while Drogba and Bosingwa are accused of being in breach of the principles of sportsmanship by insulting the referee by making offensive comments.

‘‘The club and the individuals concerned have been requested to file a statement by Friday May 29.’’ UEFA’s Control & Disciplinary Body will deal with the case on June 17.

Meanwhile, Guus Hiddink is determined to end his league campaign in charge of Chelsea with a victory tomorrow, even if it sends Sunderland into the Coca-Cola Championship.
