Chelsea boss Jose Mourinho believes Louis van Gaal will bring success to Manchester United.
The pair worked together at Barcelona.
Speaking on Goals on Sunday on Sky Sports Mourinho said: "He is a fantastic coach and it's easy for me to say as I know him so well and he is a fantastic person
"He will have time to make Manchester United win titles again. This season they still gave a chance to do that with the FA Cup and they also have the opportunity to finish in the top four and go back to the Champions League, which is the minimum for a team like them."
