To the surprise of some, considering they were once team-mates, Mikel Arteta and Mesut Ozil failed to see eye-to-eye once the Spaniard became Arsenal boss.
Many had hoped the appointment of Arteta would inspire a significant upturn in form from Ozil after a year-and-a-half of struggles under previous manager Unai Emery, but instead, his former Gunners colleague went one better and axed the German playmaker from the fold altogether.
After opting to omit Ozil from Arsenal's 25-man Premier League squad, the World Cup winner left for Fenerbahce in January of 2021. Rumours were rife regarding why Arteta didn't want to keep the midfielder, but it is believed the former Real Madrid man's lack of versatility played a huge part in his decision.
