Ruben Amorim rushed to the Selhurst Park dressing room at halftime, with Manchester United down 1-0 after a poor first half. Whatever he said at halftime seemed to spark a change.

After a shaky November threatened to undo October's progress, United fought back to defeat a tired Crystal Palace. In what is always a long season, this victory was crucial to stop the slump, especially after a worrisome first-half showing in Croydon.

Before this game, United had won only once in their last 11 Premier League away matches—that was against Liverpool at Anfield last month. Amorim mentioned in the pre-match press talk that he wasn't sure why his team struggled away from home, but he emphasized that his players needed to close out games better.

Amorim left Patrick Dorgu out of the starting eleven, admitting he saw anxiety from the defender when he had the ball. Diogo Dalot took his place, but even Dalot hasn't been convincing at left wing-back this season.

Shea Lacey, 18, was the only attacking player on the bench. Kobbie Mainoo has played as a No. 10 at times, but Amorim has said he sees him mainly as a defensive midfielder. Before the game, only Arsenal (with six) had allowed fewer goals than Palace (nine) in the Premier League this season, and United had been toothless in attack against Everton earlier in the week.

Still, United had no excuse for not attacking on Sunday. Palace played against Strasbourg in France on Thursday, giving them just two days to prepare, unlike United's five days at Carrington. So, United came to Selhurst Park with a slight advantage.

Bryan Mbeumo patted Amad on the back as they headed back to the locker room before kickoff. Amad assisted Mbeumo against both Liverpool and Tottenham, making their link-up seem like a key factor again in this game. Though the pair were not at their best, United still clinched a win.

Dalot made a bigger impact in the first 30 seconds than Dorgu had in 58 minutes against Everton, launching a long throw into the box, but Casemiro failed to score from it.

The away fans sang '12 Days of Cantona' for two clear reasons: December was approaching fast, and the stadium was the site of Cantona’s infamous kung fu kick.

Amorim looked annoyed as Palace started creating chances. He paced the sideline, and the fourth official reminded him to stay in his coaching box. Soon after, Mbeumo got a yellow card for throwing the ball down in frustration.

Adam Wharton fired a shot right at Senne Lammens from just outside the box. Then Jean-Philippe Mateta missed an easy chance after Yoro’s mistake, and Yoro later blocked Yeremy Pino's shot. Yoro managed to recover after his earlier error that led to Mateta's opportunity.

Mateta kept causing trouble. He physically dominated Matthijs de Ligt and forced another mistake from Yoro, who fouled him unnecessarily in the box, giving away a clear penalty.

Mateta scored the penalty, but it was called back for a double touch. The rule that allows a retake after a failed penalty needs to be reconsidered. Anyway, Mateta made the second penalty.

"Boom, boom, Mateta's in the room" was chanted to the tune of the Vengaboys song twice in a row. This should have pushed United to respond strongly, but instead, they walked slowly off the field at halftime. Amad and Mbeumo weren't playing well, and United often struggle when those two don't perform.

Luke Shaw shook his head as the halftime whistle blew. Shaw, who has been at United for 11 years and was playing his 300th game for the club, played under five permanent managers during his time at Old Trafford. He might have been close to playing for another if United hadn't managed to turn things around. At least there won't be any big investigation on Monday morning.

Amorim made two halftime subs, and they paid off. Dalot played great, and Mason Mount scored a fantastic goal to put United up 2-1. It was a bold choice for Amorim to keep playing Joshua Zirkzee, but he proved right when the Dutchman scored a nice half-volley to bring the score level.

Zirkzee's shot had to be powerful to get past Dean Henderson—and it was. Since arriving from Bologna, Zirkzee hasn't always looked like a top striker, but if he can score more goals like that for United, he'll do just fine.

The Everton game was awful, and Amorim absolutely had to find a solution; in this game, he did.

Ruben Amorim must have been relieved. Somehow, Manchester United managed to beat Crystal Palace at their home for the first time in the Premier League since February. It also ended United's five-year wait for a win at this stadium, especially after a first half where Palace should have been way ahead.

Oliver Glasner’s team was strong and deserved to lead because of Jean-Philippe Mateta’s penalty. Still, they couldn't take advantage of their dominance. United, who hadn't scored against Palace in their previous four league games, suddenly scored twice in nine minutes through Joshua Zirkzee and Mason Mount to win the game.

It was a bad day for Glasner, who had a tough week and had been mentioned as a possible candidate for United in the past. Plus, Ismaïla Sarr had to leave the game with an injury before halftime. Amorim, on the other hand, probably kept his cool as he went to the locker room after the game. But he must have been happy inside after United's better play, which moved them above Palace to sixth place.

Amorim didn't want to compare his tactics with Glasner’s before the game, but he did say that Palace was doing things better than us. After their loss to 10-man Everton, he changed both wing-backs. Amad Diallo moved to the right, and Diogo Dalot replaced Patrick Dorgu because the Danish player admitted he feels anxious when wearing a United jersey.

After playing against Strasbourg in the Conference League, Glasner asked Palace’s players to keep going, even though it's getting close to the end of November. Even though they could have won if they had taken their chances, he'll be worried about how much their performance dropped after they fell behind.

United must have seen a chance to win, since they had three more days to get ready. They almost scored after just 43 seconds when a long throw caused trouble in Palace's area, but Dean Henderson, the former United goalie, made a great save to stop Casemiro.

That close call woke up Palace after the early start time for TV. Soon, they had many chances. After missing a lot of opportunities, Mateta missed two shots in the first 15 minutes. Adam Wharton also shot straight at Senne Lammens after a corner before setting up a great move that ended with a bad shot from Daichi Kamada.

But after contract talks stalled, Mateta scored. Another good pass from Wharton caused Leny Yoro to foul Mateta in the box. Mateta scored the penalty, but it was called back by VAR for touching the ball twice. A change in the rules now allows a re-take if the initial penalty is good, and Mateta scored again.

With Zirkzee isolated in attack, United couldn't respond and should have been further behind at halftime. Luke Shaw blocked a shot from Pino, and Eddie Nketiah hesitated when he had a clear chance on goal, and the chance was gone.

Henderson wore a baseball cap to shield his eyes from the sun, but he probably wasn't happy to let United tie the game eight minutes into the second half. Palace was caught off guard by a quick free kick from Bruno Fernandes, and Zirkzee chested the ball down and shot it into the far corner. He and the United fans were surprised.

After a scramble in front of the goal where Zirkzee almost scored on his own net, United's day got better. A few minutes later, Marc Guéhi fouled Zirkzee on the edge of Palace’s box. There was a pause in the wall when Fernandes passed the free kick to Mount, who scored past Henderson.

Without Sarr's speed, Palace barely had any more chances, and United held on for a big win.
