Barcelona coach Xavi Hernandez warned his team on Tuesday that their Copa del Rey semi-final opponents Real Madrid would be coming to wage a “footballing war” at Camp Nou. 

The Catalans hold a 1-0 lead from the first leg and have beaten their rivals in each of the last three Clasicos. “It doesn’t mean anything that we have won the last three Clasicos, tomorrow is another footballing war,” Xavi told reporters.
