You guys underrate Arsenal so much that you don't even see their success when it's right there that the are winning. They might have more loss among the top three teams but they manage their so well to win instead of draw like the other teams did. They are were topping th table even before now, came down and still went back there. If it was that easy, Manchester United would be there dragging the top of the tree with them, but they aren't even sure of going to the Europa conference league next season, give Arsenal some respect they deserve.
Bukayo Saka is one of the key players of Arsenal, he can't fade injury just when the club need him the most but even if he wouldn't be around, there are people that will take that wing position massively and will deliver. He was injured some weeks back and wasn't here and yet the team were breaking barriers like he was present in the club, take a chill and watch the outcome of the match.
Nobody is saying that Arsenal is a weak team, and in fact it is difficult to say that about the team that currently leads the Premier League. The fact is that the Premier League is very competitive, and Liverpool and City are too close, besides, the situation at the top of the table changes very often, recently Liverpool was the leader, today Arsenal, and I would not be surprised if City soon will up in first place. The teams are moving very close, which of course improves the quality of the championship.
