Former Manchester United goalkeeper Peter Schmeichel has criticised the "idiots" whose protests forced the Red Devils' game with Liverpool to be called off.
United fans broke into Old Trafford in a demonstration against the Glazer family before their side's proposed clash with Liverpool, and the game had to be postponed following the protests.
A police officer was left needing emergency treatment after fans stormed the Old Trafford pitch, and Schmeichel believes that those who took part in the protests are not "die-hard" United fans.
Speaking to CBS Sports, Schmeichel said: "I don't think the die-hard fans were the ones inside the stadium. I think they are idiots, troublemakers.
"None of them will remember the good times. Some of them weren't even born when the Glazers took over the club.
"The die-hard fans, the true fans, keep voicing your opinions, but keep it at a proper level. Don't be stupid about it. Don't demand something which is unrealistic. Keep up the pressure, keep up the ideas.
"What we've learned from the last two weeks is, if we stand together and we show our opposition to ideas that we don't agree with, as a massive group, it does have an effect. I think football, not Manchester United, is at a crossroads now.
"There is this incredible opportunity now to change direction. Something that I think it has needed for a long, long, long time."
Man United could reportedly be facing a points deduction and other sanctions from the Premier League and FA following the protests.
