Zlatan Ibrahimovic says - Cristiano Ronaldo, Lionel Messi and I are the only three players who can make a difference.

The enigmatic Swede who played his football with PSG - has also contributed to the book about the managers he has played for during his career including incoming Man United boss Jose Mourinho and former Barcelona and Bayern Munich coach - Pep Guardiola

Subtlety is not Zlatan Ibrahimovic's strongest suit. One day on the training ground, Ibrahimovic thought that one of the young players had not given his best to the session.

At the end of training Ibrahimovic called this guy over and said, 'Now, you have to go home and write in your diary that you trained with Zlatan Ibrahimovic today, because I think it could be the last time that you do.'

Maybe he's not so diplomatic, but he's a winner. The biggest problem I had with him was on the training ground.

Even at the training sessions he didn't want to lose anything — ever. He's always fighting, always 100 per cent. He can only be one way, direct.

If Zlatan doesn't like something, he's going to tell you. With the young players he could be too strong, so I told him that he had to take care of them because he was an example for them. I explained that a bit of subtlety was required, as it is not always effective to speak too strongly with the young.

Zlatan Ibrahimovic is never afraid to speak the truth to anyone, even me. On one occasion we were speaking about Hernan Crespo who was, in my opinion, an outstanding striker.

When I asked Ibrahimovic what he thought, he said, 'Yes, he's a striker, but he cannot make the difference. There are only three players who make the difference: Zlatan Ibrahimovic, Lionel Messi and  Christiano Ronaldo.'

Such is his confidence, and he is correct to think it. Ibrahimovic is one of the few strikers, maybe the only one, who is just as happy when he makes an assist as he is when he scores.

He is one of the most unselfish players I have met, which is of massive value to the team.

At Paris Saint-Germain I began to bring in players with the right mentality. In the first summer we signed Zlatan, a top player and highly professional.

Sometimes it's the players who have to be the leaders, not the manager, and Ibrahimovic immediately became the leader in the dressing room. It was why I wanted him.

I spoke with him and explained the situation at the club and how important he could be in the dressing room.

'You can be a good example for all the others,' I said. 'You have experience, talent, personality; you have character and in this sense you can be fantastic.'

Sometimes too much is made of the captaincy in football but it can be important. Some players want to be captain and they grow even more if you give it to them.

Other don't want, or need, to be captain — they are the natural leaders.
When I offered Ibrahimovic the captaincy at PSG, he refused it, saying he was not sure how long he would stay at the club, so to be captain would be wrong. But that didn't stop him being a natural leader through his personality.
