Xavi attacked the Chelsea manager's tactics while in charge of Real.
"I donāt want people to think that Iām always attacking Mourinho, thatās not my intention, but obviously I donāt like the way his teams play on the pitch,ā the 33-year-old revealed to Sport.
"It annoyed me to see them play like that as they had an idea and a concept before. [Zinedine] Zidane, Roberto Carlos - they were incredible.
"They dominated every area of the pitch. You had to look at the facts and just admit they were better. It was the same with the Madrid side in the 'Quinta del Buitre' era, another amazing team with a clear and sound philosophy.
"A big club can't play like Mourinho's Madrid. We donāt let the pitch dry up so it turns into a āpotato fieldā, nor do we kick the other team 30,000 times or try to turn up the heat in a game. We didnāt even do that when Madrid went above us.
"Weāve won, drawn and lost, but always according to a footballing philosophy. The result is an impostor; it goes beyond winning and losing."
