This evening is the second "go" at the 4th round FA Cup match between these 2 teams. This one is at Old Trafford as the first tie at the Abbey Stadium in Cambridge resulted in a nil:nil draw. A replay is great for Cambridge - think of the money for new players - although a win is perhaps far too much to hope. Good luck Cambridge United!

UPDATE 2320z: Sadly Cambridge United lost 3:0 to Manchester United. Never mind. It is certainly no disgrace to be knocked out by the much richer club. They must now focus on the league.
