Sutton United takes on Arsenal in the fifth-round fixture at the Gander Green Lane, as the non-league side look to cause a huge upset against the 12-time winners of the competition. Sutton have already defeated three Football League teams to reach this stage, with their scalp of Championship high-flyers Leeds United in round four causing the biggest stir. Arsene Wenger will be wary of taking tonight's opponents lightly, and may go against his usual cup policy of blooding the young players, with the artificial turf at the Borough Sports Ground adding an extra layer of unpredictability to the contest. (Kick-off 7.55pm).
