Based on Manchester United current formation, I don't think Amorim is fixing this team. In the last four matches, he's consistently brought on Sesko from the bench, which I don't think is a good decision. They were just lucky to win this match, otherwise, there was nothing impressive about their performance today. His tactics aren't favorable, and if this is the way he wants to play, they won't go far in the league table. He has a lot to do to improve this team to compete like other top teams. So far, they've only faced Arsenal as a strong team, and that was the one match where Manchester United performed well, despite losing. The rest of their matches have been disappointing. Does this mean Amorim is only good at playing against strong teams?
Not really, perhaps Amorim is just having trouble choosing a more appropriate formation for his current players because those strong teams play more structured, which can lead Manchester United to that kind of play, even if they ultimately lose. But when facing a less strong team like yesterday, Manchester United didn't play much better and only won thanks to luck, with penalties and an own goal. I'd also like to see Amorim use a different formation than usual so we can all see a slightly different result than what Manchester United are currently experiencing.
