The striker looks set be reunited with former boss Mourinho - who he worked with at Serie A side Inter Milan   
Jose Mourinho is the disciplinarian. Everything with him is a mind game — he likes to manipulate. Such tricks were new for me, all the time doing one thing to get another thing, all the time triggering me.
I like these games and they worked for me — I was top scorer under him and we won the league.
The way Mourinho prepared for games was also new to me. I would get pumped up, believing the story he would feed us. I went through a lot of adrenaline when I played for him. It was like nothing was ever good enough.
He gave and he took. Jose Mourinho knows how to treat a footballer, but Carlo Ancelotti knows how to treat a person.
 He is always well-informed about opponents, going through their every weakness and every quality, and then the way he wanted the game to be. If he wanted to kill the game, he'd kill the game; if he wanted the game to be open, it would be open.
For Mourinho, it was all about winning. He knows that winning is the only thing, though it seems his third season at clubs often presents a problem for him.

The Jose Mourinho earthquake will hit Manchester imminently and a tsunami of even greater force is expected to follow. Zlatan Ibrahimovic is in his sights and it could be a spectacular combination: the self-proclaimed Special One — and a striker who tweeted on his departure from PSG 'I came like a king, I left a legend.' Taken from his autobiography I am Zlatan Ibrahimovic, previously serialised in Sportsmail, here is Zlatan on all the egos heading for Manchester this summer.
On his passion for Mourinho
He once gave the flip chart a kick and sent it flying across the room, and the adrenaline pumped inside us, and we went out like rabid animals. I felt increasingly that this guy gives everything for the team, so I want to give everything for him. People were willing to kill for him.
Jose's obsession
He works twice as hard as the rest. Lives and breathes football 24/7. I've never met a manager with that kind of knowledge of the opposition; it was everything, right down to the third-choice goalkeeper's shoe size.
Pre-match theatre
He built us up before matches. It was like theatre, a psychological game. He might show videos where we'd played badly and say: 'So miserable! Hopeless! Those guys can't be you. They must be your brothers'. And we nodded, we were ashamed. He would say: 'Go out there like hungry lions. In the first battle you'll be like this (he'd pound his fist into the palm of his hand) and then in the second battle you will be like this…'
Jose the misery
There was one thing that really bothered me — no matter what I did there was never any hint of a smile. I was doing totally amazing things but Mourinho had a face like a wet weekend. I scored an insane goal, later voted goal of the year, but Mourinho stood there stony-faced. What the hell is it with that man? What gets him going? One way or another I was going to make that man cheer. It happened, but only after we had won three titles and I was top scorer.
A smile at last!
After our success, the man of stone, the man who never batted an eyelid, had woken up. He was like a madman. Cheering like a schoolboy and I smiled. So, I got you going, after all. But it took some doing.
On Clashing with Guardiola
He looked at me as if it was my fault. He glared as if there had been a disturbance, like I was an alien. He was a brick wall and I never saw any signs of life from him and every hour I wished I could be out of there.
Why he didn't fancy a move to City
When I was forced to leave Barcelona by Guardiola in 2010, sure I knew all the incredible things that had happened at Manchester City and all the money seemed to be there since the crew from the UAE (Abu Dhabi) had taken over. City could surely become big within a few years but I didn't have the time for long-term plans and money was never a big thing. I wanted to go to a club that could be good now and there was no club with a history like AC Milan.
Not following his orders
Guardiola had told me: 'Here in Barcelona we don't turn up to training sessions in Porsches or Ferraris.' Messi, Xavi, Iniesta, the whole gang — they were like schoolboys. The best footballers in the world stood there with their heads bowed — it was ridiculous. One day, I jumped in my Ferrari Enzo and parked up right in front of the door to the training facility.
