Everton manager Roberto Martinez has described Chelsea boss Jose Mourinho as one of the world's best coaches ahead of Saturday's match at Goodison Park.
The Spaniard is happy to see the 'Special One' return to England and thinks his skills as a coach make him one of the best in the game.
Martinez is also happy with his side's progress since his arrival from Wigan Athletic in the summer, replacing David Moyes.
"The players have shown real strength in trying to do things in a different way and we have done things very well. (But) in football you can only consider satisfaction when you win the three points. You need to do that," he said.
Martinez's Wigan side were not known for their defensive stability but were capable of producing effective counter-attacks, and at times, played some expansive, skilful football, much like in their FA Cup final victory over Manchester City.
"One thing is playing a certain way, and the other is being very good at it - it needs time and I have been very impressed in the way we have played the first three games," he added.
However, under David Moyes, Everton were very rigid in their positioning and were often characterised by their long-ball tactics, utilising the height of players like Sylvain Distin, Marouane Felllaini, Nikica Jelavic and Victor Anichebe.
The former Swansea City coach has so far attempted to employ a continental style of play at the clubs he has managed.
Martinez' side face a tough test on Saturday evening and the Everton coach will be looking forward to pitting his wits against the man who has won every league he's managed in.
"He [Mourinho] is one of the best managers in world football, there is no denial of that. Our league wants that and it is good for everyone to have the best at each job," he concluded.
