Andres Iniesta believes newly-appointed Chelsea boss Jose Mourinho "damaged Spanish football" during his time at Real Madrid.
Mourinho recently sealed his return to Stamford Bridge following a turbulent three years at the Santiago Bernabeu.
Iniesta insists the Portuguese tactician has left a negative legacy in La Liga, despite winning back the title from Barcelona in the 2011-12 season in record-breaking fashion.
"You just have to look at the facts," Iniesta told El Pais. "Yes he damaged Spanish football, in general more harm than good.
"But I don't like talking about that person at all. So if you don't mind we'll leave it at that."
Iniesta's comments follow those of Barcelona team-mate Xavi, who criticised Mourinho's tactics while in Madrid.
