Arsenal has gained some revenge over Liverpool with a 2-1 win in their English FA Cup 5th round tie in London.
The Gunners were beaten 5-1 by Liverpool in the Premier League last weekend.
The Londoners will be at home again in the quarter-finals, having been drawn against Liverpool's local rivals Everton.
Arsenal were in control when they led 2-nil shortly after halftime, Alex Oxlade-Chamberlain scoring the first goal after 16 minutes and then setting up the second for Lukas Podolski.
Podolski then conceded a penalty for a trip on Luis Suarez and it was converted by Liverpool captain Steven Gerrard in the 60th minute.
Liverpool felt they should have had another penalty for an Oxlade-Chamberlain challenge on Uruguayan Suarez soon after but World Cup referee Howard Webb turned down their strong appeals.
Earlier Everton beat Swansea 3-1 and Sheffield United beat beat Nottingham Forest 3-1.
United will play either Sheffield Wednesday or Charlton in the last eight.
In the other quarter-finals, FA Cup holders Wigan play Manchester City in a repeat of last season's final, while Brighton or Hull City will play Sunderland.
