Barcelona vice-president Carles Vilarrubi has hit out at Jose Mourinho and claims he will be a 'disaster' if, as expected, he returns to Chelsea after announcing his departure from Real Madrid.
Mourinho is ready to bid farewell to Spanish football after three eventful years at Santiago Bernabeu.
The enigmatic Portuguese coach has courted controversy throughout his time in Madrid, with regular clashes with arch-rivals Barca seeing him hit the headlines for events on and off the field.
Vilarrubi says no-one in Spain will miss Mourinho and his antics when he has gone and feels the Premier League would be ill-advised to welcome him back with open arms - six years after he brought a successful three-year stint at Stamford Bridge to a close.
The Barca chief told The Daily Telegraph: "It is not good for English football. Chelsea maybe think they had a good time from him in the past, but you will see the real Mourinho now.
"If he behaves like he did in Spain it will only be an unhappy relationship. A disaster. And at his age he is not going to change.
"My position is not because he was the coach of a rival, but because of who he is and what he did. His three years in Spain he only creates disagreements, arguments. There is nothing positive he brings.
"You can learn good things about life from watching people in football, or the circus, or the opera. There was nothing he brought that was good. There was no positive balance. I cannot see anything good about him. Not one thing. In sporting terms, maybe I am not the person to ask. But in cultural terms, he was a disaster.
"Apart from his aggression to the coach of Barca, the ambience he creates everywhere he goes, the relations with the players, with the press, are absolutely terrible. I am happy that he is leaving. And so is everyone in Spanish football.
"I am just glad he has gone. I am not interested in him. Go leave, goodbye."
