MADRID (AFP) - European champions Barcelona have apologised for the behaviour of their players after a number of the star-studded squad interrupted a press conference by screaming whilst dressed in Halloween costumes.

The group, including Luis Suarez and Neymar, burst in on Getafe midfielder Victor Rodriguez's press conference after Barca had beaten the Madrid side 2-0 on Saturday.

"In no case was it our aim to offend or bother any colleagues in the Getafe team," Barca said in a statement on Sunday.

"The interruption in the mixed zone which coincided with Victor Rodriguez's press conference was an unfortunate and involuntary coincidence for which we personally apologise and wish to express to him our respect."
