Several Barca identities have attacked Mourinho since his departure from Real.
"I feel really bad for Iker because he doesn't deserve to be treated like that and I have seen how it has affected him. We've talked more than ever this year," Xavi told El Pais.
"It's not the fact that he hasn't played that's the problem; the worst thing is the comments. He hasn't been shown the respect he deserves.
"How can Mourinho say that his mistake was not signing a new goalkeeper two years earlier? I guess he doesn't remember, but Iker won them the Copa del Rey in Valencia with three amazing saves."
