The fourth round of the cup starts with arguably the biggest match-up you could have in the tournament.
The Gunners and the Red Devils are the most successful teams in the entire history of the tournament, with Arsenal winning 13 times over Man United’s 12. They are the only two sides to reach double figures in terms of winning the cup (next are Chelsea and Spurs with eight wins each). In terms of the table, both sides are on the same points, with Arsenal three goals ahead in fifth place. However, Man United are on a great run of form under Ole Gunnar Solskjaer, and are also the defending champions.
Arsenal v Manchester United is on BBC One at 19.30 (kick-off 19.55).
