Louis van Gaal blames Manchester United executive vice-chairman Ed Woodward for his departure from the club in 2016, describing him as "the evil genius" behind his sacking.
The Dutch head coach replaced David Moyes at Old Trafford in 2014 but lasted just two years in the job despite winning the FA Cup in his final game in charge.
After guiding United to fourth place in the Premier League in his first season, Van Gaal saw his side slip down to fifth the following campaign as he failed to convince the club that he could turn their fortunes around.
