You rarely see something shocking in soccer these days, but two teammates going at each other's throats is up there.

That's what Idrissa Gueye and Michael Keane did, reminding people of Lee Bowyer and Kieron Dyer—or David Batty and Graeme Le Saux for those who remember.

What made it even crazier was that Everton started well. This wild incident in the 13th minute happened just after Manchester United's first move into Everton's side of the field.

Bryan Mbeumo lost the ball, and Gueye's bad pass to Keane let Bruno Fernandes shoot from a ways out, but he missed.

The argument between Gueye, who is 5 ft 9 in, and Keane, who is 6 ft 3 in, got heated when Gueye slapped his teammate in the face and then tried again.

It reminded some of when Bowyer fought with his Newcastle teammate Dyer, resulting in both being sent off against Aston Villa in April 2005. Also, Batty and Le Saux's fight when Blackburn lost to Spartak Moscow a decade before that.

Idrissa Gueye was kicked out of the game for slapping Everton teammate Michael Keane in a weird incident.

Being down a player didn't stop the visitors, as Kiernan Dewsbury-Hall's goal won the match for the 10 men.

Referee Tony Harrington, who had only stepped in to calm down James Tarkowski and Joshua Zirkzee before, immediately showed Gueye a red card, kicking him out of the game.

Even then, goalkeeper Jordan Pickford had to hold back the 36-year-old as he almost completely lost it. It was a really dumb move, and Gueye is lucky his team played so well to win.

This fight happened just after Everton captain Seamus Coleman, looking sad, went straight to the locker room because his start, which was in two months, lasted less than 10 minutes. Everyone thought the game would now be in United's hands.

But give credit to David Moyes's team. They got it together and scored a great goal just before halftime.

James Garner, who used to play for United, passed to Kiernan Dewsbury-Hall. He shrugged off a weak challenge from Fernandes, stepped past Leny Yoro, and shot an amazing ball from the edge of the box, which Senne Lammens could only help into the top corner.

This gave David Moyes his first Premier League win at Old Trafford in 18 tries against his old club. It also ended Ruben Amorim's five-match winning streak, which made people hopeful leading up to the anniversary of his first game as manager.

A win could have moved United up to fourth place. Instead, they're still in 10th, tied with Moyes's team, after not winning for the third game in a row.

Amorim wasn't fooled by United's short hot streak. After they won 4-0 against Everton last season, he warned that things would get rough, and he said before this game that the rough patch wasn't over. Once again, he was right.

Joshua Zirkzee had United's best chance, but Jordan Pickford made an excellent save.

United's recent wins under Ruben Amorim ended with a loss at Old Trafford.

United looked weirdly quiet in the first half, even though they had an extra player.

Without Benjamin Sesko and Matheus Cunha—whose injury was revealed by Visit Altrincham's social media when he couldn't turn on the Christmas lights—Zirkzee started for the first time in a long time and didn't take advantage of it.

If Cunha and Sesko get healthy soon, it would make sense for the unhappy player to go on loan in January to get the playing time he needs before the World Cup.

Everton threatened twice through Iliman Ndiaye before Gueye's crazy act, and they deserved their lead with 10 players.

United pushed back before halftime. Patrick Dorgu missed a shot from Zirkzee's cross, Amad Diallo shot right at Pickford, and the England keeper made another excellent save to block another long shot from Fernandes.

Amorim put Lisandro Martinez in the squad for the first time since February and put him on the bench with Shea Lacey, and made changes to try to turn the game around.

Mason Mount came on at halftime, and Kobbie Mainoo and Diogo Dalot followed soon after. Everton, expecting a strong attack, fought hard to hold on.

Keane was involved in another play when his leg tripped Mbeumo in the penalty area, but VAR correctly said that Keane touched the ball.

Everton snapped a long losing streak at Old Trafford, winning there for the first time since 2013.

Mbeumo then forced Pickford to make a good save before Fernandes missed from close range.

Zirkzee nearly saved United when his header was saved by Pickford, who then made another fine save from Zirkzee as England manager Thomas Tuchel watched. Everton held on until the end.

Overall, it was an amazing win for Moyes's team—and Idrissa Gueye should be thankful.
