Arsenal 4 - 1 Bolton Wanderers

Arsenal beat ten-man Bolton 4-1 at Emirates Stadium to keep up the pressure on Premier League leaders Chelsea.

Laurent Koscielny bundled home his first Arsenal goal after 24 minutes, only for the French defender's poor back header to allow Bolton to equalise just before half-time through Johan Elmander.

Marouane Chamakh headed the hosts back in front, with Gary Cahill then sent off for a tackle from behind on the Moroccan.

Alex Song netted Arsenal's 1,000th Premier League goal under manager Arsene Wenger and substitute Carlos Vela stroked in number four with seven minutes left.
