Playing at home and dominating in a match is very common for Arsenal, especially what Arsenal are facing is a rather weak team this season, namely Chelsea. And conceding one goal also doesn't matter much for Arsenal if their closest rivals can now win all their remaining games this season. Even if Arsenal's closest rivals have lost once again in the remaining matches this season, Arsenal will also not get a championship trophy this season even though they are able to win all the remaining matches.
Arsenal can only do their best by continuing to maintain victory points in the remaining matches. Man City has the advantage with a difference of 2 matches from Arsenal that have not been played. and that makes Arsenal's position will only depend on luck alone. they certainly pray for Man City to face several defeats in the remaining matches. because Man City also has a busy schedule, and of course that will affect the performance of their players.
but Arsenal must show his best game in the rest of the season. trophy or not Arsenal should be able to ensure it this season. but they are too careless.
