Louis van Gaal has hit back at criticism from Angel Di Maria over the manager's handling of him whilethe pair were at Manchester United.
Van Gall splashed out £60million on the Argentina international in 2014, but Di Maria lasted only one season, making 32 appearances, before moving on to Paris Saint-Germain.
The winger had accused van Gaal of failing to get the best out of him by using him in the wrong positions, but the Dutchman insisted the issue lay with Di Maria.
Van Gaal told BBC Sport: 'Di Maria says it was my problem. I played him in every attacking position.
'You can check that. He never convinced me in any of those positions.
'He could not deal with the continuous pressure on the ball in the Premier League. That was his problem.'
Van Gaal, who announced his retirement aged after 40 years in football, also defended his decision to purchase Bastian Schweinsteiger and Radamel Falcao.
German midfielder Schweinsteiger played just 35 times during 18 months at Old Trafford, while striker Falcao endured a miserable loan spell, scoring four goals in 29 appearances.
Van Gaal said: 'I brought Schweinsteiger in because we needed a captain on the pitch. He didn't do it. He was injured. He had an excuse.
'I wanted a first-class striker. I don't want to go through all the names but when you can't have the first or second choice, you have to be happy with the fourth or fifth, so Falcao came into the picture but we knew in advance he was injured.
'That is why I said we should take him on loan.'
