The Glazer family assumed control at Old Trafford in 2005 but have rarely encountered a trouble-free period in charge. Factions of support have persistently protested against their ownership owing to concerns over debt levels, with others believing United can no longer match their Premier League rivals in the transfer market as a result.
But speaking to a number of national newspapers during his side's pre-season tour of South Africa, Ferguson has stuck up for the American family.
"I am comfortable with the Glazer situation. They have been great," he said. "They have always backed me whenever I have asked them. I have never faced any opposition.
"They have always been as sensible as they can be in terms of financing the club. They have to invest in the team to maintain the value of their asset.
"When the Glazers took over here there was dissatisfaction, so there have always been pockets of supporters who have their views. But I think the majority of real fans will look at it realistically and say it's not affecting the team. We've won four championships since they've been there, one European Cup."
