Departing Manchester United chief executive David Gill has paid tribute to the club's owners, the Glazer family.
Gill claims United's success proves the determination of the Glazers to keep things progressing on and off the pitch, and that some of the criticism they get is unfair.
He said: "The Glazers have definitely demonstrated that since they have taken over they have shown that what happens on the pitch is crucial to the club's ambitions off it.
"There are still a small number of dissenters and they will always be there and they have had long held views which they are not going to change. We respect those, but ultimately, someone has to own the club.
"They [Glazers] get the personal enjoyment and the important thing is that there is really no ego about them. They operate behind the scenes here, they don't walk around saying "we own the club", and they are very mindful of the traditions and the history of the club and people.
"Clearly, if you own an asset and it comes up with winning a 20th title, it's unbelievable."
