The Dutchman believes the Special One can recapture former glories in west London with the right backing from Roman Abramovich, and is unsurprised Frank Lampard is stayingJose Mourinho and Chelsea can once again rule English football, once the Portuguese boss completes his imminent return to Stamford Bridge.
Last month Goal revealed Mourinho has agreed to return to the club where he won back-to-back Premier League titles, a League Cup and an FA Cup in three years.
And Robben insists that, with the right backing from owner Roman Abramovich, the Special One can re-establish the Blues as the dominant force in the Premier League.
“It is a big move for Chelsea with Jose coming back – but I know it is one the fans will welcome,” the Dutchman told reporters.
“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.”
Robben is also unsurprised by the fact that Frank Lampard has committed himself to one more year at Stamford Bridge after lengthy and, at times, tortuous contract negotiations.
“It is no surprise to me that Frank is now staying,” he added.
“It can not be for football reasons that he was going – because he is still one of the best – it must have been a personal thing with the old coach.
“As soon as it became clear Jose would return, there was never any chance Frank would go because there is such respect and friendship between the two of them.
“He sent me a text after we won the final – that is the sort of classy guy Frank is.”
