Andreas Iniesta has claimed Jose Mourinho created an unbearable atmosphere between Barcelona and Real Madrid players when he was in charge at the Santiago Bernabeu.
The former Barcelona star called time on a glittering career with the Catalan giants at the end of last season and now plays for Japanese side Vissel Kobe.
Speaking about the animosity between the two Spanish teams on Monday, Iniesta told La Sexta: “You don’t have to be for Barcelona or Real Madrid to know that the situation was unpleasant.
“And the key component in that story was Mourinho. Whoever doesn’t want to see that, is radical.
“You didn’t see the rivalry that always existed before, it went beyond that, you saw hate. That atmosphere developed and it was unbearable.
“The Barca-Madrid tension caused by Mourinho did much damage to the national team [Spain] and the teammates.”
