Manchester City still have the firepower even against Arsenal they displayed a lot of it. Arsenal where more defensive and containing the city side, while city where more aggressive in the attack. Of course I will give it to arteta for his brilliant performance, at least it was much better than last season. Also for city side, these guys have been on the winning side week in week out, i believe most of their players might as well suffer from fatigue, and it's natural in football because if Kevin De Bruyne had been on that midfield, trust me we will be having a different conversation here, because Arsenal where really on the lucky side of that game.
That match was a tactical match from two tacticians. Arteta has understand the errors Pep and Manchester City were waiting for just as they did against Arsenal last season home and away, Arsenal played very well but small error gave Manchester City the chance to score Arsenal, that was Arteta avoided in the match that is why the match looks annoying because it seems like both the teams were defending their home; and at end, Arsenal were lucky to win the match.
Arsenal is will now remain the tough opponent for Manchester City and will be the only team alongside with Tottenham that will likely win the Premier League this season.
