There's plenty of bitter history between Manchester United star Zlatan Ibrahimovic and Manchester City boss Pep Guardiola.

The former Barcelona duo will come face-to-face on Saturday.

Ibrahimovic pulled no punches in his autobiography when he described his relationship with Guardiola.

“It was war and it was me against him," he wrote. “Guardiola the frightened little over-thinker who couldn't even look me in the eye or say good morning."

He also claimed Guardiola has a “hang-up" with Jose Mourinho, even though he has come out on top in seven of their 16 encounters as managers, drawing six and losing only three.

“Guardiola had a hang-up about Mourinho," said Ibrahimovic. “Mourinho is a big star. He's the opposite of Guardiola.

“If Mourinho lights up a room, Guardiola draws the curtains. I guessed that Guardiola was trying to match up to him. Hatred and revenge get me going."
