UEFA sends Collina to monitor Barca-Madrid clash

UEFA is sending Italian refereeing great Pierluigi Collina to

monitor Belgian match official Frank de Bleeckere’s handling of a

potentially volatile Champions League semifinals clash between

Barcelona and Real Madrid.

UEFA has named Collina, its head of referees, as official

observer at the Camp Nou on Tuesday.

After Barcelona won a bad-tempered first leg 2-0, Madrid made a

failed protest to UEFA about German referee Wolfgang Stark sending

off Pepe when the game was scoreless.

Collina was referee when the clubs last met in a Champions

League semifinals, second-leg match.

In 2002, the sides drew 1-1 in Madrid allowing Real to advance

and win the title.

Collina also refereed the 2002 World Cup final.
