Diego Maradona believes Jose Mourinho is the best manager in world football.

The former Argentina, Napoli and Barcelona star says Chelsea boss Mourinho is the classiest operator in the game and even holds an advantage over Bayern Munich's Pep Guardiola who some rate as better than the Portuguese.

"Mourinho is a friend of mine," Maradona said in an interview with Sky Sports.

"For me, Mourinho is the greatest without a shadow of a doubt because he knows what you're going to say before you say it.

"It's extremely dangerous! That's what makes him Mourinho. That's what makes him the greatest.

"Pep or Mourinho? I say Mourinho. I think Pep needs a little more time, as Mourinho has had, to be Mourinho."
