It is expected that Mourinho will leave Real in the summer, with his former club Chelsea and Paris St-Germain battling for his signature.
Granero still hopes he stays at the Bernabeu whatever happens tomorrow night and told the London Evening Standard: “He came to Real when they were behind Barcelona and he managed to beat them in his first season in the Spanish Cup.
“In his second year he helped them win La Liga with 100 points while they set a new record scoring 121 goals. This is amazing. We were behind Barcelona when he came, after two years we were over them. That shows a lot.
“I would be happy if he stays at Real. I am a supporter and I want this big manager to be our manager. But if he leaves and comes to England it is going to be good for the Premier League.”
