Bukayo Saka willingness to learn makes him a coach's dream, according to Mikel Arteta.
The 18-year-old was thrown into a new role at left back when he replaced the injured Sead Kolasinac against Manchester City, and the absence of Kieran Tierney means he's now played the last four games in the back four.
Saka rose through our academy ranks as an attacking player - and has two first-team goals to his name this season - but he's had to rein in those instincts and develop the defensive game of his game.
Arteta says that Saka's attitude has been spot-on.
