Arsenal are the best team in England. They’ve lost one game, and that was against United. In that game, they were good but still managed to lose 3-1. They are a better side today, but so are United.
United can still get a win or draw if they keep it tight. Unfortunately, Casemiro is out due to picking up a fifth yellow card of the season against Crystal Palace. All indications are that Martial and Dalot are still not 100%. Here’s the side we expect.

An old-fashioned smash-and-grab 0-1 would be lovely. Bonus points if it’s controversial enough to make Arteta’s blood boil. A draw or better would be a good day.
Prediction: 2-2
