And Calderon told Sky Sports' Revista De La Liga: "I think his departure was expected by everyone, taking into account the situation over the last year.
"It has been very difficult and his behaviour has not been right. Listening to the president, I don't think Mourinho will be happy with what he said about him not being able to cope with the pressure.
"He's not that kind of person. He likes the pressure and he is happy with that. I don't think Mourinho is one of those people who suffers with pressure.
"On the contrary, he feels happy with that and he feels like the star. He likes that. I will admit it's not nice for Mourinho but I think his character has made it more difficult.
"But it's true that the situation came to a point now and it was not easy to keep him at the club. I don't know if they really had an agreement or whether it was Real Madrid that decided to sack him. I'm not sure.
"I'm really excited to know what Mourinho is going to say after the president said he couldn't cope with the pressure.
"He must be very angry at this moment and I can't wait to hear what he says when he is in England."
