Isco has accused ex-Sevilla sporting director, Monchi of “grabbing him by the neck” during a heated argument last year.
He has now opened up on his bitter relationship with Monchi in an explosive interview.
Isco claims Monchi, who is now president of football operations at Aston Villa, was the driving force behind his acrimonious exit.
“I told him he was the biggest liar I’d ever met in the world of football and he assaulted me,” Isco told Marca.
“Although I was sorry because I had a very good relationship with my teammates and the fans treated me wonderfully, I couldn’t be comfortable in a club where the sports director attacks me and nobody speaks up or apologises.
“Not after the aggression, after all the lies he was leaking. So I forgave my contract and left.”
