Arrived on a free transfer from Schalke in 2017 and hit the ground running with his powerful performances at left-back. However, he has since struggled for fitness, been plagued with injuries and looks half the player he was. Although the Bosnian would add depth to the left-back position, Kieran Tierney would be ahead of him and Bukayo Saka has also impressed in his position. When all three are available for selection, Kolasinac would be third choice in my opinion – and that’s if Arsenal don’t add another player in his position this summer. Sell.
