Arsenal have beaten Liverpool 2-1 in their FA Cup fifth-round tie and will now play Everton in the quarter-finals.
There was an early opening for the Reds when Steven Gerrard found Daniel Sturridge, but the striker saw his tame effort saved by Lukasz Fabianski.
The away side had another good chance to take the lead moments later. Luis Suarez scooped a pass into the feet of Sturridge, who then rounded Fabianski. However, his shot from a tight angle went wide.
The Gunners made the breakthrough soon after and it was Alex Oxlade-Chamberlain who got the goal. Yaya Sanogo had a shot saved by Brad Jones, but the 20-year-old was there to convert the rebound.
Fabianski kept out Suarez with his feet early in the second half, but Oxlade-Chamberlain combined with Mesut Ozil to set up Lukas Podolski, who swept home.
However, Podolski then fouled Suarez inside the box to concede a penalty. Gerrard stepped up and sent Fabianski the wrong way.
Despite huffing and puffing, and Daniel Agger heading wide, the visitors were unable to find a second goal.
