Robbie Burton and Folarin Balogun scored as Arsenal came from two goals down to draw 2-2 at Derby County and stay level on points with Division 1 leaders Chelsea.
Chris Martin gave hosts Derby the lead just before half-time at Pride Park with a superb free-kick.
Alex Babos made it 2-0 on the hour but Burton reduced the deficit 10 minutes later with a shot into the bottom corner from the edge of the box.
Substitute Balogun capitalised on a defensive error to equalise in the 79th minute with his fourth goal of the season.
The result keeps Arsenal second, level on points with Chelsea who drew 2-2 against third-placed Tottenham Hotspur. Derby move up to fourth, one point behind the Gunners.
