Miguel Herrera has been fired as Mexico coach following allegations that he punched a television reporter.
Former Arsenal midfielder Abou Diaby has rejected an offer to join West Brom in favour of finding a new club in France.
Sir Alex Ferguson insists he was right to remain at Manchester United following the Glazer family's controversial takeover in 2005.
Former chief executive David Gill had previously put his name to a statement condemning the Glazers' approach as it would pitch United into vast amounts of debt.
When the buy-out was completed, Ferguson was contacted by an influential fans' group member and told he had to resign.
The Scot refused to comply and, speaking to Channel Four News, Ferguson said it had been the correct course of action.
"The Glazers are supportive. You always appreciate people who support you and they have been very good," said the Scot.
"Everything I have asked for they have delivered, and they supported the club in all the improvements they made.
"Look at the training ground today. It is probably the best training ground in Britain. That is down to the Glazers.
"They have produced the medical centre. It is absolutely fantastic.
"What can you do? (Staying) was the right thing to do."
Ferguson has maintained a pragmatic stance about the Glazers' involvement, stating repeatedly down the years that once United became a publicly-floated company, it was always ripe for a takeover.
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."
What Ferguson did have a problem with was his dealings with the media.
Although he said he bore no grudges to the press, he did ban some organisations fairly regularly.
The BBC were frozen out for seven years after they refused to apologise for the content of a documentary about his son Jason, and his alleged influence at United.
"He was an agent for about a year and a half," said Ferguson. "Then he gave it up.
"It was a two-hour documentary. It was horrible.
"They never apologised. That was the problem.
"You have to have some sort of strength of principle. I didn't enjoy it. It wasn't correct, accurate or honest."
