Why did Zlatan Ibrahimovic leave Barcelona?

Answer 1

He didn't fit in thier style they thougth he could change him but they couldnt. All the mifilders in barcelona and forward are small and short so it would really bad having a huge 6ft3 giant in the team simply didnt go with tiki taka style he is more of a individual just like ronaldo.

There was an intervew about him why he left barcelona he said "the only problem i had with barcelona was Gurdiola he didnt talk to me or motivate me he also said that when he was in inter milan mourinho would motivate him and he would kill for him.

With Ibra as the #9, Messi had to play the Right Wing, a spot where he isn't doing wonderfully. The 4-3-3 front for Barca looks like Pedro-Ibra-Messi, forcing Iniesta to play a bit deeper with Xavi and Busquets. This meant Keita had a hard time fitting in. Also, despite that team upfront, Messi and Pedro had more goals than Ibra.

Raiola is Ibra's agent. He quickly saw things going bad in Barcelona and did not want his client to be such a public "bust". Hence, he worked hard, smartly and quickly to get Ibra out of there.
