FA Cup rescue acts

Crossan. After keeper Jim Montgomery complained of concussion when blocking a Law shot, United took full advantage with two goals inside the last four minutes from Bobby Charlton and Best and Law almost won it.

1964: Sunderland 2 United 2
A match that became the stuff of legend in the North East with some reckoning it was watched by a record Roker Park crowd despite the official attendance of 46,727. With a couple of minutes of extra time left, Charlton set up a second replay, which the Reds won 5-1, thanks to a crucial header that silenced the masses on the terraces.

1962: United 2 Bolton 1
Wanderers led for a long spell in this third-round tie through Dennis Stevens but David Herd appeared to have forced a draw in the 83rd minute despite looking suspiciously offside. However, there was still time for Jimmy Nicholson to send the crowd wild with a last-gasp winner, firing in off a post, and exacting some revenge for the last meeting in the competition - the 1958 final.

1955: Reading 1 United 1
Allenby Chilton's own goal was proving costly at Elm Park until Colin Webster saved the Reds with only five minutes left. The Welshman's strike enabled United to cruise home in the snow-affected replay 4-1 but his team were lucky in the first game with Wally Hinshelwood missing three good chances to kill the tie off.
