Manchester United chief executive David Gill believes the Glazer family's Old Trafford takeover helped the club to clinch another Premiership title.
Bryan, Avram and Joel Glazer have reason to celebrate
The Glazers took control in the summer of 2005 and Gill told BBC Five Live: "Their ownership has brought stability and we are all benefiting from that.
"They have got involved in areas where they feel they can add value.
"But in other, football, areas they have allowed manager Sir Alex Ferguson and others to get on with it."
After American tycoon Malcolm Glazer completed his takeover he appointed sons Joel, Avram and Bryan as non-executive directors - but some fans voiced fears over the future of United.
However, last October a Glazer spokesman told BBC Sport that the family were committed to making the club a success.
Gill said that he spoke to the Glazers on Sunday after United won the Premiership crown as a result of Chelsea's 1-1 draw at Arsenal.
Winning the title is a fantastic achievement
He added: "They are delighted - and so they should be. They are sports fans and they know what running a sports club is all about.
"All the doomsayers who said we would be in trouble have been proved wrong."
And as well as hailing the Glazer's contribution to United's first title in four years, Gill heaped praise on boss Ferguson, who proved his decision not to retire in 2002 was the right one.
"Alex is a winner," said Gill. "He is very experienced and still has that motivation after many, many years.
"He has a great eye for spotting talent - he is second to none in that area.
"We have brought in 10 or 12 players since 2003, and Alex has done that very well - bringing in young payers who fit into the way Manchester United play.
"The team has changed a lot in the last three years. Winning the title is a fantastic achievement."
And Gill claimed that winning the title has also tempered the disappointment felt after United went out of the Champions League to AC Milan in the semi-finals.
"We were very disappointed after losing to Milan, but we've worked very hard to win the Premiership and for me that is the benchmark," he said.
"Everyone is delighted to have won it again having not won it for four years."
