The Dutch legend is not impressed with the tactics of the Portuguese coach, who failed to lead his side to the Champions League final against Pep Guardiola's club
Cruyff wrote in his weekly El Periodico de Catalunya column: "Real Madrid's recent La Liga results prove that Barcelona did a great job in the Champions League. Madrid comfortably beat Athletic Bilbao, Valencia and Sevilla in away games, which is not easy.
"They were four intense Clasicos. The mental aspect was perhaps even more tiresome than the physical aspect, mainly because of Mourinho. It's something from the past now, but Mourinho didn't get a single decision right, both on and off the pitch."
Cruyff then went on to state that the Real Madrid coach is obsessed with Barcelona, adding: "I don't want to pay too much attention to Mourinho and his 'Barcelonitis' any more. His special tactics to disrupt Barcelona are behind us now.
"He wouldn't have had to change his tactics if he had faith in his own players. Nevertheless, every coach is responsible for his own decisions."
Barcelona progressed to the final of the Champions League by beating Real Madrid 3-1 on aggregate.
