Madrid, May 7 (AFP) Real Madrid coach Jose Mourinho will boycott the club's press conferences until UEFA inform him why he has been banned for three matches, his assistant, Aitor Karanka, revealed.

UEFA handed a three-match European ban to Mourinho after he made allegations of favouritism towards bitter rivals and Champions League conquerors Barcelona.

Mourinho, already banned from the touchline for Tuesday's Champions League semi-final second leg at Camp Nou, which cemented Real's exit 3-1 on aggregate, will have a further one-match ban suspended for three years.

Karanka yesterday said Mourinho "would defend himself until the end" and announced that the outspoken Portuguese would make no further media appearances until European football's governing body justified the sanction against him.

"UEFA is the one imposing the punishment and as of today they have not said the reason why the coach was punished," Karanka told a post-training session news conference.
