Even if Manchester City drop points, they can recover those points later on and they have been particularly good towards the end of the season which has helped them to the top of the points table. Arsenal but if they lose some points in the middle or early part of the season, they cannot recover those points later and this is where they fall behind. It is difficult for us to distinguish how much better Arsenal are performing this season compared to last season.
Last season if they had most of the original XI in their XI then they might have performed better than this season but this season despite being injury free this team has not done well. However, this team is well aware that there is room for improvement and they will prepare accordingly for the upcoming season.
Throughout this season Manchester City suffered three defeats against Wolves, Arsenal and Aston Villa. Losing nine points in these three matches should be able to be used by Arsenal to catch up with the points that Manchester City has collected. Arsenal wasted too many opportunities to collect full points when Manchester City slipped, they were unable to maintain a consistent performance which made it easy for Manchester City to collect the most points.
Arsenal weakness in the last two seasons lies in its inconsistent performance. Arteta can almost make Arsenal win the EPL trophy with improved performance after bringing in several quality players. Next season you must have the ability to maintain your best performance to win the EPL trophy.
