The American owners of the Tampa Bay Buccaneers NFL franchise spotted the club's massive commercial potential and have exploited it to the maximum, leaving it, according to Ferguson, vying with Real Madrid as the world's biggest club.
And as time went on, Ferguson felt the structure of the club was a lot easier to work with than it had been before.
"The only thing I had to do was make sure they would let me buy players in the same level as I always had," he told the BBC.
"I always said about United, they would always find the money.
"When I came to the club, we could only buy players through season ticket money.
"My first signings were Brian McClair and Viv Anderson. That was season ticket money.
"It wasn't until we became a PLC that the ability to buy bigger became obvious.
"There was no interference from the Glazers. David Gill was always the conduit to buy a player.
"I just carried on. I had no issues about it at all."
