Despite playing versus 10 men for over an hour, Arsenal needed an own goal to beat Newcastle United, giving Arsene Wenger cause for concern.
Arsene Wenger conceded that Arsenal was "a little bit cautious" in Saturday's 1-0 Premier League win over Newcastle United.
The visitors dominated the game at St. James' Park and were aided by Aleksandar Mitrovic's 16th-minute dismissal, but still required a Fabricio Coloccini own goal to take the points.
Manager Wenger was happy that his side enjoyed such a strong control of proceedings, but is eager to see more attacking threat in future.
