Mikel Arteta has previously said that this summer is the time "to go to another level" in the transfer market, but he will now know more than ever before that top-quality first-team regulars aren't the only targets the club must pursue.
On top of his squad already being short in certain positions, qualification for Europe and the introduction of five substitutions next season mean the Spaniard must look to add rotational options to his side in order to prevent a repeat of what has happened during the current campaign.
Injuries and a lack of numbers have seen young academy talents fill up the spots on the bench regularly, with Zak Swanson, Mazeed Ogungbo, Charlie Patino, Marcelo Flores and Omari Hutchinson called up to first-team duties on a number of occasions. While this can be seen as a positive reward for their progress, it is important that there remains a healthy amount of established and experienced options to choose from.
