Two teams nicknamed the Red Devils meet at Old Trafford where the Premier League leaders face the Blue Square Premier's second-placed side. United have conceded only eight goals in their last 15 FA Cup matches and not more than once in a game during that sequence.

Middlesbrough were the last team to score two goals against United in the FA Cup, in a sixth round tie in 2007, when the teams drew 2-2 but United won 1-0 in the replay. Crawley are only the sixth non-league since World War Two to reach the fifth Round and none of those sides have progressed further. But the last three non-league teams to play against Manchester United in the FA Cup have earned a replay.

United have not conceded a goal in their last four FA Cup matches against non-league opposition. This is the first time Crawley have ever played a top flight team in the FA Cup.  In their run-up to the biggest game in their history, Crawley have beaten Newport County, Guiseley, Swindon, Derby and Torquay.

Crawley's Matt Tubbs has scored three goals in five games in this season's FA Cup. There have been three red cards in Crawley's last three FA Cup matches. United will be without Park Ji-Sung, ruled out with a hamstring strain, while Rio Ferdinand is unlikely to be ready with a calf strain. Owen Hargreaves, Antonio Valencia and Johnny Evans are also absent for the Premier League leaders.
