Former Manchester United manager Louis van Gaal has aimed a stinging attack at Ed Woodward - claiming he knows 'zero' about football.
The Dutchman was axed by United in 2016 just two days after guiding the club to the FA Cup.
Van Gaal, 67, has blamed United's chief executive for the club's problems and says he simply isn't up to the job.
Woodward has come in for criticism again this season after United's disappointing campaign.
Van Gaal, who has also had spells in charge of Ajax, Bayern Munich, Barcelona and Holland, told German magazine 11 Freunde: "At Bayern, the people in charge are football men. I always appreciated that.
"At Manchester United , on the other hand, Ed Woodward was installed as CEO - somebody with zero understanding of football who was previously an investment banker.
"It cannot be a good thing when a club is run solely from a commercially-driven perspective.
"I don't hold it against the club. They wanted Mourinho and he was on the market."
Van Gaal guided United to fourth and fifth-placed finishes during his time at Old Trafford but never really won over the Red Devils supporters.
The Dutchman added: "Appointing Mourinho was obviously interesting from a business point of view.
"He wins games. And for a club like United, the main thing is to win trophies.
"How they are won isn't the main priority, the English fans see it differently.
"They accept that the game is not all about attacking but it is also about defending.
"I always tried to defend high up the pitch, to be in the opposition's half and play the game there."
