FORMER Manchester United captain Gary Neville said Sunday's protests against the Glazer family should be a spark for further reform in English football and urged the controversial owners to sell the Red Devils.

The clash with Liverpool had to be postponed on safety grounds after fans broke into Old Trafford and invaded the pitch, with the Premier League condemning "the actions of a minority".

Long-standing anger with the Glazers has increased in intensity since it emerged United were one of the driving forces behind the breakaway European Super League, which collapsed within 48 hours due to huge, unrelenting pressure.

Bury-born Neville said the Glazers should do "the honourable thing" and sell up.

"This is a consequence of the Manchester United owners' actions two weeks ago," the former United defender said. "There is a general distrust and dislike of the owners, but they weren't protesting two or three weeks ago.

"The Glazer family are struggling to meet the financial requirements at this club and the fans are saying that their time is up.

"My view is quite simply that they're going to make a fortune if they sell the club and, if they were to put it up for sale now, I think the time would be right, and it would be the honourable thing to do.

"There's huge discontent, not just across Manchester United fans, but I think for football fans up and down the country and I think they are just saying enough is enough.

"The Glazer family have been resilient and stubborn for many, many years. I think they are struggling to meet the financial demands that this club needs and have done for some time."

The former England international said the protest had to spark reform if it was to achieve anything meaningful.

"Beyond today, it should be about reform and regulation and making sure they can't do it again," he said.

"Protesting is the right of every single person in this country. However, beyond today, it's about making sure fans across the country unite to make sure that there is reform in English football. That's the most important thing.

"Today will be a waste of time if there isn't reform in English football."
