The Gunners boss liked what he saw from the side's younger players as they fought back to claim a convincing victory
Arsenal manager Mikel Arteta has stressed Joe Willock's chance to impress in the Premier League will come after the youngster once again impressed in the club's 4-1 win over Molde in the Europa League on Thursday.
The 21-year-old helped the Gunners overturn an early deficit by forcing two own goals before rounding out the scoring in the 88th minute.
Willock has featured in all three of Arsenal's Europa League games to date but is yet to make a Premier League appearance for Arteta's side this campaign.
