The match with Manchester City is a biggest one for Arsenal in rest of season as they are two direct competitors for the Premier League crown. Arteta and Arsenal don't have to win that match, they need to have a draw, prevent Manchester City to reduce 5 points gap and move on to collect points from other teams.
Don't think like that there are still 10 weeks to go, it's mean Manchester City can earn maximum of 30 points, it's enough to beat Arsenal at the top position. Arsenal always lost against Manchester City, so Arsenal still need to win regardless they're currently in a quite safe position and 8 points difference than Manchester City.
Maybe Arsenal have a slight advantage since Manchester City need to play at the other leagues, but it can put a pressure for Arsenal's players since Arteta will force them to win in this league, otherwise Arsenal will not get anything in this season.
Arsenal take an 8 points lead in the Premier League race into the international break, but for sure Manchester City will not let them rest easy as the campaign unfolds. Time and again this season, Arsenal have hit a crossroads and the same fear has surfaced, if they’ll bottle the league or win it. But one thing about this Arsenal side is that when they think they’ll drop their steam, they come through unbowed, if not unscathed. Now they’re all focused on the league title so they are going to eye the run-in with a healthier blend of caution and confidence. For Manchester city, the biggest issue facing them is the number of games that have to be wedged into the next eight weeks. 11 in the league, add an FA Cup semi-final against Sheffield United and a potential two-legged Champions League semi-final and it will be hectic. So I think fighting on three fronts could put City at a disadvantage against Arsenal, who only have eyes on the title.
After Arsenal's relegation from the Europa League, they are only focused on the EPL... With 8 points to spare against Man City, I think they will be League champions this season... Man City really have a lot of challenges where they need to perform well... I think the Champions League is more important for them...
