AMAD DIALLO was sent off for a second caution after taking off his shirt off following his last-gasp FA Cup winner.

The Manchester United winger’s actions were silly because referee John Brooks had NO option but to show a red card for his celebration.

Amad Diallo is shown a red card after celebrating his winning goal against Liverpool

This law came in because of players making political statements.

It wasn’t the case here, so I’d like to see the law changed as fans want goals and emotional celebrations.

If Brooks showed common sense, he’d have been rapped by his bosses for failing to apply the law correctly.

After the game, Diallo admitted he forgot that he was on a yellow card.

But he wasn’t going to let the dismissal put a dampener on his day.

He told ITV: “What a game. Today I think we deserved this win. One of the best games of the season so I’m very happy. It was an important moment, I think it was the best goal of my career.

“I don’t believe, but this is football so you need to believe every moment. When he (Garnacho) gave me the ball I wanted to give it to him again but I shot.

“I forgot the first yellow so I’m really disappointed to get the red card but the most important for me was to get the win.

“Everyone came to me and said I deserved it. The most important [thing] for me today was the win.”

United won a thrilling contest at Old Trafford 4-3.

After just ten minutes, Scott McTominay’s goal gave them the ideal start.

However, a swift double from Alexis Mac Allister and Mo Salah by Liverpool before halftime completely changed the course of the match.

With three minutes remaining, Antony tied the score for United, but the visitors should have already won the match.

Harvey Elliot gave Liverpool the lead back in extra time, but Marcus Rashford pulled his team even again.

Then, with 120 minutes remaining, Ivory Coast winger Diallo broke free to score his team’s fourth goal and give them a historic triumph.
