Arsenal booked their place in the FA Cup quarter-finals with a 2-0 fifth-round victory over Sutton United at Gander Green Lane on Monday.
- Sutton United 0 Arsenal 2
- Perez gives Gunners the lead
- Ospina shaky for Wenger's side
- Walcott scores landmark goal
- Deacon denied by the woodwork
Arsene Wenger expressed concerns about the non-league club's plastic pitch and his team started cautiously, but they finally found the breakthrough on 27 minutes with the opener from Lucas Perez and took a one-goal lead into the half-time break.
The Gunners quickly doubled their advantage 10 minutes into the second half as Theo Walcott pounced from close range to notch his 100th goal for the Premier League giants, who set up a last-eight date with another fifth-tier side in Lincoln City.
The visitors survived and early scare when the U's had a penalty appeal waved away when Craig Eastmond went down in a clash with Nacho Monreal.
But Wenger's side grew more accustomed to the conditions and broke the deadlock in the 27th minute through Perez, who was fortunate to see his low cross from the left find the bottom-right corner after Walcott had stepped over the ball.
Walcott then had a chance to make it 2-0 soon afterwards as the hosts failed to clear their lines at the back, but the England winger fired over the crossbar.
After Alex Iwobi missed the target by inches with a deflected effort following a counter, Paul Doswell's men almost equalised just before half-time when David Ospina gave away possession, but Adam May was unable to capitalise on the mistake as he fired into the side-netting.
However, an early goal from the north Londoners in the second half gave them some breathing space. Monreal sent in a cross from the left, which deflected into the path of Walcott, who crashed home on the half-volley from six yards out.
The National League outfit looked for a response with nothing to lose as Maxime Biamou hit a tame shot at Ospina, who then misjudged a corner which let in Jamie Collins, but he somehow missed the target from point-blank range.
The woodwork then came to the Gunners' rescue on 65 minutes when their former youth player, Roarie Deacon, let fly from long range, and although his shot had the beating of Ospina, the crossbar denied him a memorable goal.
There were no further scares for the joint-record winners of the competition, who will face the Imps in the more familiar surroundings of the Emirates Stadium.
