Thomas Vermaelen is fit to face Manchester United.
The Belgian defender was a major doubt for today's game after hobbling off at Aston Villa in midweek with a leg injury. But Vermaelen will take his place alongside William Gallas in the centre of Arsenal's defence.
Alex Song also starts today after returning from the Africa Cup of Nations. He replaces Aaron Ramsey, while Samir Nasri comes in for the injured Eduardo.
Sol Campbell, tipped to deputise for Vermaelen ahead of the game, is not involved.
