Fans can't believe Casemiro wasn't shown a second yellow card against Luton

Fans online can't believe Casemiro wasn't shown a second yellow card against Luton Town.

Casemiro was extremely lucky to escape a red card in the first-half for Manchester United's Premier League fixture at Luton.

The experienced midfielder was booked for tripping Amari'i Bell in the 34th minute and committed another foul moments later.

However, match referee David Coote failed to brandish another yellow card, which of course would have resulted in a red card.

Luton players and Rob Edwards couldn't believe Coote did not show the Brazilian a second caution following his tackle from behind on Ross Barkley right in front of the official.

Substitutes Scott McTominay, Sofyan Amrabat and Christian Eriksen immediately started to warm up on the sideline following Casemiro's lucky escape, hinting at a possible change to avoid going a man down.

One X user wrote: "Oh Casemiro should be sent off there. That’s a yellow card if he wasn’t already on a yellow."

A second tweeted: "Textbook second yellow challenge by Casemiro. Coote has absolutely bottled that."

A third added: "Casemiro is lucky. Not a second yellow imo but he’s so stupid - he has one more chance basically."

A fourth said: "Casemiro’s lucky there. He never just takes a step back when he’s on a yellow."

Another commented: "Coote as I've said often is a coward. It has to be a yellow for Casemiro. But Coote always tries to avoid making decisions. More so than any other referee."

Man United lead 2-1 at the break. Rasmus Hojlund bagged a quick-fire brace as Carlton Morris pulled one back.
