The pair worked together for three years at Barcelona but will go head-to-head this season, with Van Gaal having taken the reins at Old Trafford following a successful World Cup with Netherlands.
He has also won titles in Spain, the Netherlands and Germany with Barca, Ajax and Bayern Munich and said at his introductory news conference that he is aiming to add England to that list.
Mourinho -- whose Inter Milan side beat Van Gaal's Bayern in the 2010 Champions League final - and Chelsea will be among the main rivals standing in his way.

"I watched him at his press conference and he was pure Van Gaal -- honest and open, the way he always is.
"He is a very, very good coach, he'll be great for Manchester United. We are both great coaches. It's what we were born to do.
"Louis was the best coach in the World Cup and he is a good friend -- really, a friend for life. I have deep respect for this man.
"He is in the best period of his career. With coaching, if you deal with winning and losing in the right way, you improve. He analyses every experience. He has got better and better.''
