Unai Emery was impressed with Alex Iwobi's performance in Saturday's 2-1 win at Huddersfield Town, but he still thinks the Nigerian has room for improvement.
Iwobi scored the opening goal at the John Smith's Stadium, his volley deflecting in off Terence Kongolo following a left-wing cross from Sead Kolasinac.
It was his third Premier League goal of the season, matching his total for last term despite making seven fewer starts.
The 22-year-old looked particularly bright at the start of the campaign and appeared to have adapted well to Emery's system following the departure of Arsene Wenger.
