After conceding 11 goals in four games, it could be defensive frailties that end up costing Arsenal in the Premier League title race, thus decisions have to be made in the summer transfer window.
Regardless of how this season finishes, if the Gunners want to mount another title challenge in the 2023/34 campaign and give a good account of themselves in the Champions League they'll need to tighten up at the back otherwise it will almost certainly prove to be a factor that stops them from achieving success.
Of course, with the summer transfer window just around the corner, Mikel Arteta's side are being linked with defensive reinforcements as Ivan Fresneda, Josip Sutalo and Devyne Rensch are just a few names that have been tipped to arrive at the Emirates Stadium in the next few months.
