Robben was part of the side which collected back-to-back Premier League silverware at Stamford Bridge.
And one of his favourite assets of the Special One was that he does not care who he upsets - as long as he wins.
Robben explained to the People: "It is a big move for Chelsea with Jose coming back - but I know it is one the fans will welcome.
"He had very successful years at Chelsea - and he can have them again.
"The thing about Jose is that he will win at any cost - he doesn't care how, he just wants to win.
"I've not always been supportive of the style of football he plays, but he is a winner who has achieved great success. I am sure that with some big signings from the owner that Jose and Chelsea can rule England again."
