Mikel Arteta must learn Arsenal lesson after repeating Thomas Tuchel Chelsea mistake

Arsenal's performances this season have been a credit not only to the club but the manager who has been entrusted to implement his vision on the football club.

However, this past week has shown us that Mikel Arteta still has lessons to learn if he is going to push the Gunners to that next level and bring silverware to the Emirates Stadium. Arsenal were sleepwalking to the Champions League exit door on Wednesday night and it was little surprise when Joshua Kimmich scored to seal Bayern Munich's spot in the last four.

Plan A was not working for Arsenal in midweek but sadly there is no Plan B. Arteta has stayed loyal to his best XI this season which is admirable but it means that there is a lack of players in the squad capable of coming off the bench to alter the game.

Take Eddie Nketiah for example. He has made a respectable 27 appearances in the Premier League for Arsenal this season but delve deeper into his playing time and it tells a different story.

The young forward has completed 90 minutes just three times this season in the top flight and since the turn of the year, the most amount of minutes he has played in one match is 24. Yet the 24-year-old is still being picked on the bench on the off chance he can change the game for Arsenal.

Nketiah is not the only one, Emile Smith-Rowe and Reiss Nelson have also been underplayed this season and it shows when they eventually feature. It is not the first time this has happened at different clubs.

Wednesday's victorious Bayern manager Thomas Tuchel suffered the same problems when he was at Chelsea. He remained loyal to a certain set of players and it eventually all unravelled as the seasons wore on.

With a Premier League club's schedule now more congested than ever, Arteta needs to learn the art of rotation if his team is to take the next step. Pep Guardiola has mastered this at Manchester City with the likes of Rico Lewis and Oscar Bobb able to slot into the first team when needed and not look out of place.

How Arteta learns from this past week's disappointment will shape whether or not he can be the man to bring good times back to North London.
