Hopes were high for Kieran Tierney when Arsenal were the team to entice him away from his boyhood club Celtic in 2019, but to say the move has been a success would be generous.
The Scotland international has come up with some memorable moments for the Gunners since his switch and established himself as one of the most important players within Mikel Arteta's system when fit. However, 'when' and 'fit' are very much the key words when discussing Tierney's time in North London.
Arteta is a huge fan of Tierney the player, during the Spaniard's first full season at the helm the left-back was arguably Arsenal's most important attacking outlet - though that is a more a damning indictment of the tactical set-up rather than Tierney's prowess.
