#1 Mesut Ozil
A lot of people have been criticising Ozil's work rate, his body posture, and his attitude towards games in general. There were even rumours saying that Ozil skipped the game against West Ham after falling out with Emery. Nacho Monreal has since clarified that there was no dispute between the German midfielder and their manager.
Regardless of what had happened, it is crucial for Ozil to step up his performance once the Premier League games start again. He has had a break these two weeks since he is no longer playing for the Germany national team. After the break, Arsenal will start having more and tougher fixtures in the coming months. The team will have to travel to face opponents in Europa League and the Carabao Cup.
The toughest match in the month of September is probably the game against Watford where the Gunners will be the host. The Hornets remain unbeaten since the opening match-day and even beat Tottenham 2-1 at home. There is no doubt about Ozil's creativity and talent as a midfielder. The real challenge is for him to replicate his high-level of performance in every single match. As compared to Eden Hazard or even Roberto Firmino, the 29-year-old is lacking consistency in his games.
Emery must find a way to motivate his midfielder to be confident in himself and get more involved in the game. It is easy for Ozil to be uninvolved as soon as Arsenal loses possession. As time goes by, it becomes harder and harder for him to get his momentum back. One thing that fans will truly want to see is Ozil improving his game in the upcoming fixtures.
