The Blancos coach has taken another swipe at his counterpart in Camp Nou, insisting that the Barca trainer is fully aware of how he attained his successes in the last few years.Jose Mourinho has once again implied that Barcelona are being favoured by referees as he feels the Catalans have been getting key decisions lately in La Liga and the Champions League.The Real Madrid coach previously hit out at the Camp Nou side after they defeated AC Milan in the quarter-finals to advance to the last four when he suggested that Barca were a certainty for the final because of Uefa\'s help.\"[Pep] Guardiola is an intelligent kid and he knows how he has won so many matches in the various championships. He knows exactly how he has done it,\" Mourinho was quoted as saying by Sky Italia.The Portuguese boss then looked back at his side\'s 2-1 loss in the first leg of their Champions League semi-final against Bayern Munich on Tuesday, and felt that Los Blancos deserved a better result at the Allianz Arena.\"I believe a draw would have been fairer, but that\'s football for you: whoever scores wins. It doesn\'t matter if you do so in the first or last minute.\"The second leg at the Santiago Bernabeu takes place on April 25.
