Ander Herrera has attacked Manchester United for not making success on the pitch its main priority.
The Spaniard spent five years at the Theatre of Dreams and became a favourite among supporters ahead of joining Paris Saint-Germain on a free transfer over the summer.
Meanwhile, many have sought to explain United's continued failure on the pitch this season through pointing out the proclivity of vice-chairman Ed Woodward to place too much emphasis on hitting short-term financial targets and not enough time on a long-term football project.
Reflecting on his time at Old Trafford, Herrera told So Foot: "I was very happy at that incredible club. I am very grateful to the supporters.
"Frankly, I was immensely happy in Manchester, but at the club, there were times when I felt that football was not considered the most important thing."
United, who sit 10th in the Premier League table after 11 games, meet Brighton & Hove Albion on Sunday.
Herrera was open to staying at United but ultimately moved to PSG after the former stalled on offering him a two-year contract.
