A narrow difference in points like this probably won't make Arsenal really calm because Manchester City can easily shift them at the top of the standings at any time, next week Arsenal will face Southampton, of course they have to win the game if they want to keep their distance from Manchester City because after the meeting with Southampton next they will meet Manchester City which will obviously be difficult to win because during the last meeting Arsenal always lost.
It's not just about the Etihad game. Arsenal still have to play the high-flying Brighton and Newcastle as well. Arsenal will most likely drop points in this match, therefore not winning today is quite crucial. while Man City's attack looks relatively easier. So of course it's not over yet, but the ball is in Man City's hands.
Although whatever is possible, but I doubt this. Arsenal performance is decreasing while Man City us now progressing very much better. They are also in their great condition, they really did well in some matches previously both in EPL and UCL. So, this will be hard for Arsenal.
Arsenal really lwaste their chance because of tje draw result against West ham yesterday. While Man City won awesomly.
This draw is very influential for the Arsenal team even though Arsenal are still 4 points ahead. But in Arsenal's game against West ham it wasn't just points that were lost, it was the way they cracked under pressure. Saka missed a spot-kick, showing vulnerability in blowing the lead in successive weeks, the pressure only getting worse. It's unrealistic to expect things to be easier. Things are likely to only get worse for Arsenal.
