Looking at this Arsenal squad, honestly I think that are good enough to challenge with their current squad (provided they do not discard Thomas Partey). Squad rotation, game management, Mentality & tactical flexibility are the key aspects that should be improved going into the season as I see excuses of injuries being their major setback last season. They came to winning the title and I’m seeing them going again this season. I wish them a successful season.
Arsenal must think about how to get a replacement player with the same quality of play. or the coach has to be careful to rotate players otherwise they will get tired and end up very easy to get injured.
Arsenal players at the end of the season actually lost their focus and several suffered injuries although not confirmed to be fatal injuries. but they felt a very big loss because they lost their momentum to get the trophy last season. and now they must prepare not to repeat it.
If Arsenal learn from their mistakes in last season I don't think they will have a problem in a new season. Arsenal performance last season was very great , the problem they was because they didn't have enough players for replacement that lead to the weakness in performance from their players. If Arsenal signs more players in addition to the players they have they still have the chance of leading the league again in nest season. Arteta is very good for the game but so unfortunate that is club lose the championship in last season, but he can succed in more players I think things will be different from how last season ended. Arsenal challenge right now is get replacement of players, if these can be done no much problem for them in next season.
