Arsenal boss Arsene Wenger has branded Aleksandar Mitrovic a "concern" for Newcastle United.
The Serbian, who joined the Magpies for £12million this summer, was sent off after just 16 minutes of his full home debut for a stamp on Francis Coquelin.
Wenger said: "Yes (Mitrovic is a concern for Newcastle).
"In the Premier League, your commitment is total but you have to play within the rules."
