Real Madrid boss Jose Mourinho dismissed complaints about the ref for tonight's Copa clash by having a fresh dig at Barcelona's past El Clasico behaviour. Barca are unhappy with the appointment of Alberto Undiano for the second-leg of tonight's Copa tie at the Nou Camp.

But Mourinho scoffed: "I prefer to stick with the lessons we have received in the past from Barcelona. Lessons in sportsmanship, how to behave in football. Not talking about the referees, not surrounding them, not demanding cards for their opponents. No cheating.

"And, of course, lessons on how to play football, they do that very well. We must 'humbly' follow that line."
