I think that anyone shall take what happened with manchester city, city can even goes very close to the arsenal in a short time. As long as MU still maintains to perform so well in EPL and im sure that MU has probability to compete for EPL this season.
We didn't know what kind of surprise that will come at the end of season. Arsenal may also able to get another bad result like the previous matches once arsenal lose the match a few times.
That will give MU and city huge opportunity to compete for EPL. MU is still potentially to win EPL even though the club was just having small chance right now. At least MU under ten hag is always performing so well.
The 3 big clubs that are currently in their best performance in my opinion Arsenal, Man City or Man United both deserve to be one of the Premier League champions. Because this season is quite difficult for me to choose, plus Arteta's competitive rivalry, Pep Guardiola and Erik Ten Hag clearly make his squad considered a team to be feared at the moment. The three of them will continue to make the opponents they face in the eyes of Man City, Arsenal or Man United considered a stepping stone that will not be allowed to go unpunished.
