The result was fair considering that Arsenal was easily the better team most of the game. The absence of Casemiro was so obvious that McTominay was just standing as a cone in the midfield in the whole game with terrible positioning and non-existence distribution. Eriksen can't do all that running as much as he tried since almost in every game, after 60-70 minutes, he is out of stamina. Antony, while he is helping with the defensive duties, he doesn't offer much in the attack because everyone figured out he is limited and predictable of what he will do, I know it's his first season in a new league and all that so hopefully with the return of Sancho (and hopefully he did some good progress), there will be more competition in that position. It's a shame that Wan-Bissaka is such a great athlete and can pull some decent tackles but his football knowledge is similar to my mom's and she never watched a football game, and his position is atrocious. I guess there is a reason Dalot is so far ahead of him. As for Weghorst, we got what we paid for, not bad at linking up with players but don't expect anything else. It's so obvious that Rashford has too much freedom from Ten Hag to produce stuff on his own, be it shooting whenever he can, dribble and all that (even tho he loses the ball a lot of times), but he is the only one that is capable of doing something like that in the team right now. Garnacho should have been brought earlier since he, together with Rashford, are the only ones from the attacking options, that can produce something out of nowhere.
The team definitely needs players and the top 2 priorities are a striker that won't go missing after being out of form or injured (hello Martial) and a central midfielder, then we can focus on depth for the bench.
Also nothing wrong with the celebration, no need to invent fantasy stories.
Edit: Also these ex United players must be the most miserable bunch of people, people like Roy Keane and Scholes are a cancer for the club since the day they retired.
