Gunners sweat on Vermaelen, Wilshere and Koscielny

Arsenal will check on the fitness of captain Thomas Vermaelen (ankle), midfielder Jack Wilshere (thigh) and defender Laurent Koscielny (calf) ahead of tomorrow’s FA Cup fifth-round tie against Blackburn at Emirates Stadium.

Full-back Carl Jenkinson is suspended after being sent off in last week’s Barclays Premier League win at Sunderland.
