The Spanish midfielder, who currently plays for Spartak Moscow, came through the youth system at the capital club and slammed the Portuguese coach for failing to win the Champions League and not blooding the youth players successfully.
"Apart from not achieving his objectives, like winning la Decima, I think that under Mourinho we saw the club’s image undermined," he told AS.

"The youth players need to have a certain mentality, given it is more likely that the club will sign somebody before putting them into the first team."
The 27-year-old went on to criticise the current level of competition in La Liga and says that he has no regrets leaving Atletico Madrid in 2010.
"[The two-team domination] only happens in Spain," Jurado observed. "In Germany it is similar because Bayern are superior to the rest, but the domination of the big two in Spain doesn’t happen in any other country.
"In my opinion we are seeing La Liga devalued because some years ago it was more competitive, more equal. Now Barcelona and Madrid are so superior it seems the rest of the teams are not motivated, because they know they have no chance of beating them.
"Although [Atletico] have won things in the last few years, I've also had a good year and won things. I don't regret any decision I've ever taken in my sporting career.
"I was actually on the verge of returning to Atleti but it didn't happen for financial reasons, as a fee could not be agreed. Today I'm glad things turned out like that because I'm happy here and feel appreciated.
"It's got better over the past few years and personally I feel better here all the time. The most important thing is that Spartak have confidence in me and they made a major commitment towards me.
"Therefore, I feel very happy and content to be in Russia. I came here because at Schalke I wasn't getting the run of games I was hoping for. Now I get all the minutes I need that I wasn't enjoying before."
