Arsene Wenger's men avoided an FA Cup shock as they came through a tricky test to secure a narrow victory at the Emirates Goals from Calum Chambers and Alexis Sanchez saw Arsenal progress to the fifth round of the FA Cup with a 2-1 win over Burnley.

Sanchez had not featured from the outset since suffering a hamstring injury at Norwich City, but set up one and scored the other either side of Sam Vokes' equaliser as Arsenal made it 14 consecutive victories in this competition.
