Arsenal hero Martin Keown fears Kieran Tierney could be growing frustrated at the club.
Keown believes Arsenal are 'not completely meeting his needs' in terms of game-time, as per The Metro.
"I feel sorry for him," Keown told BT Sport after Arsenal cruised past Bodo/Glimt. "He's a high-calibre player and he comes on in every game.
"But obviously you're not completely meeting his needs. It shows you the quality and strength of the squad when he's not starting. You want to have that competition and the level gets higher.
"Whether or not these players accept that going forward… I don't know. As long as they play like that when they come in, I think there's a future there for them."
