There are now just 16 teams left in this year's FA Cup, with Chelsea, Tottenham, West Ham and Crystal Palace booking their place in the fifth round.
They are the only four representatives from the capital remaining. Brentford, QPR and Fulham were knocked out by Everton, Peterborough and Manchester City respectively, while Arsenal were beaten by Nottingham Forest in round three.
But unlike the previous two rounds, all games in the fifth round will be played in midweek, from Monday, February 28 onwards, with March 2 currently the pencilled in date for the games.
