Wayne Rooney has claimed Louis van Gaal is 'by far the best coach I have worked with' during his illustrious career, picking the Dutchman over Sir Alex Ferguson, Jose Mourinho and Fabio Capello.
Van Gaal, who was appointed manager of the Red Devils in 2014 and led them back to the Champions League and to FA Cup glory, managed the former England captain during his two-year spell at Old Trafford.
'Van Gaal is by far the best coach I have worked with - one hundred per cent,' Rooney said, according to The Mirror.
'His tactical skills, his way of preparing and his attention to the finest of details, I found amazing.
'I admired that in him. I had never looked at stuff like that before.
Rooney admitted their relationship was not always joyous but vowed to take some of his experiences from Van Gaal into his own coaching career in the future.
He added: 'Van Gaal knows that the way he works is tough for players. I made him aware of that at the time and we talked about this very well together.
'I regret how it all ended, yet I know one thing for sure - I have learnt a lot from him and I am definitely going to use those lessons for when I am a manager.'
