United’s all-time highest goalscorer has played under four managers during his time at Old Trafford, the vast majority being during Ferguson’s tenure.
He won five Premier League titles, the Champions League once and two League Cups under the Scotsman.
But the 33-year-old has named one of his successors as the best tactical coach he has ever worked with.
Van Gaal named Rooney as his captain after Nemanja Vidic left and deployed him in a deeper role and the Englishman was full of praise for the former Bayern Munich coach when talking on talkSPORT.
“He [Van Gaal] was tactically the best I have worked with – in terms of setting you up in a shape defensively and everyone knowing their roles,” Rooney told the radio show.
“It was just about getting the attacking side right as well as the defensive side.
“He won a few trophies but it didn’t pan out the way everyone would have hoped.”
Rooney went on to explain how Ole Gunnar Solskjaer’s impact at the club has brought the good times back to Old Trafford.
The Norwegian arrived on an interim basis following the dismissal of Jose Mourinho but now looks set to land the full-time job.
“He has gone in with simplicity and has brought belief back to the fans,” the DC United forward said.
“He has made the place enjoyable again to go into work every day. The staff around Carrington are enjoying working there again and that does rub off.
“When you see the staff happy around the players, it makes it a happy environment to work in.
“He is doing a fantastic job and I’m sure he is the only candidate for Manchester United to take that job.
“It will be great to see him get it and bring some of the players he wants to bring in and keep moving the club forward.”
