Jose Mourinho is one of the best managers in the history of football. That is a fact.

The Portuguese has won the league title in four different nations: Portugal, England, Italy and Spain.

He's also lifted guided his side to the Champions League title on two occasions.

Mourinho has achieved all this while also earning a reputation of being very direct.

Whether it be with the media or his players, Mourinho usually says exactly what he's thinking.

• Chelsea's 15 African PL players ranked
• PL flops cost more than Ziyech
• The PL’s 2019-20 strikers have been ranked from ‘Elite’ to ‘Poor’

It's this man-management style that he's used throughout his career. At times it works, while at times it hasn't had the desired effect.

But what exactly does he say to his players? Kurt Zouma has recently been speaking to RMC Sport on a documentary about Mourinho.

And he told a brilliant story of when Mourinho told him he was rubbish shortly after joining Chelsea.

“He is someone who loves victory. He uses all the tools possible to achieve it," he said, per GetFrenchFootballNews.

"I came here at 19 and he played me. I was able to have my chances, I played my matches. I don’t know what other people think, we all have different opinions, but from my side, I don’t really agree (with the notion that Mourinho does not give young players a chance).

"I cannot remember which match we were playing, we were losing 3-1, away from home. The following day, he catches up with me, he takes me to his office, and he asks me if I am ok. I said yes.

"He asked me if I was sure. I said yes again. He replied: “Because you were rubbish this weekend.”

Classic Mourinho. The Portuguese brought a 19-year-old Zouma from Saint-Etienne.

But within months of Zouma arriving Mourinho was already telling him he was rubbish.

It did, however, have the desired effect as it only motivated Zouma to do better.

"Like that, direct. It shocked me, but it made me want to immediately respond (on the pitch). I remember that it hurt me, that it affected me. But I really wanted to show him that I could react.”

It's this sort of man-management that has seen him become one of the most successful managers of all time.
