Manchester United boss Jose Mourinho is slammed in the club-approved Manchester City documentary detailing last season's title success.
The Amazon Prime series 'All Or Nothing' is an eight episode behind-the-scenes series of City's romp to the Premier League crown.
And in the first episode, City midfielder Kevin de Bruyne discusses his rejection at Chelsea by Mourinho.
Describing his time at Stamford Bridge, De Bruyne says: "I was only 20 years old when I decided to sign for Chelsea, I got my chance in the first team in the first few games and I thought 'OK, everything is going well, played OK and won the games.
"One day it just stopped."
