Arsenal boss Mikel Arteta knows he faces a massive test against Tottenham counterpart Jose Mourinho on Sunday.
Arteta insists that Mourinho is still well respected as a manager and remains a proven winner who can bring success back to Tottenham.
When asked whether Mourinho was still a world class manager, Arsenal boss Arteta said: “Absolutely. They have had some ups and downs but overall you can clearly see what he wants to bring to the club.
“He manages the energy, the momentum and establishes a really strong culture in every football club. As well, he makes sure that he wins and he's won in every single club that he's been at.
“Obviously the situation and the timing when he arrived is different than starting a new project right from the summer, but I'm sure he will be successful because he always finds the right way to do it. It will take him a bit of time but I'm sure he will do it.
“He has a very clear way of playing and a very clear way of how he manages games. I think clean sheets are a big thing that he want to do, but don't forget his teams always score a lot of goals and they are really successful and he's been able to win titles because of that.
“I think in a long period they've had a lot of injuries so he hasn't had the chance to be consistent with his team and that's a big disadvantage that they have.
“I know that he's done it and I know people that have worked with him and he always find a way to be successful and I'm sure he'll do it again.
“That's probably one of the reasons that they have brought Jose in, because of his experience in dealing with those situations and having that extra edge to become a winning team."
