Louis van Gaal has criticised the structure of Manchester United and claims even Sir Alex Ferguson had "problems" with the way the club was run.
Van Gaal announced his retirement from management earlier this month, with his last job being in the hot seat for United between 2014 and 2016.
He took over from David Moyes and was given the task of restoring the Manchester club back to the glory days of which they enjoyed under Ferguson.
