Emmanuel Adebayor grabbed the winner in the 1-0 triumph over Wigan as Arsenal earned the battling victory they wanted to prove they are Barclays Premier League title contenders.
Adebayor, making his second start after returning from an ankle injury, struck in the 16th minute at the Emirates Stadium and could have added to his tally only to be denied by Chris Kirkland and the woodwork.
Gunners boss Arsene Wenger had Samir Nasri limp off after a robust challenge from Wilson Palacios but could reflect on three points that builds on last Sunday's win over Chelsea.
