AC Milan star Zlatan Ibrahimovic admits he slammed Pep Guardiola while playing for Barcelona. Aftonbladet reports that the striker reveals in his autobiography, which will be published in two weeks' time, how he told Guardiola that he was afraid of then-Inter coach Jose Mourinho and that the Barcelona coach could "go to hell".

"I yelled to him: 'You have no b****!' And probably worse things than that. And I added: 'You are sh***ing yourself about Mourinho! You can go to hell!' I was completely mad. If I were Guardiola, I would have been frightened," Ibrahimovic writes in the first chapter of his book.

The former Ajax star also took the time to reveal his true feelings for Barcelona trio Lionel Messi, Andres Iniesta and Xavi.

"The atmosphere in the dressing room was way too quiet for me. Messi, Iniesta and Xavi always obeyed without protesting. They were like schoolboys. I'm not like that and I couldn't be myself."
