When the referee blew the whistle for full time in Manchester United and Chelsea's 2-2 draw in the last eight of the FA Cup, there's a high probability that neither set of fans or players were particularly happy with the result.
In what has already been an extremely fixture-heavy month for both the European Champions and the Red Devils, a replay at Stamford Bridge was the last thing that either side would have wanted.
The match could have been settled in the first half an hour, with United storming into a two-goal lead and Chelsea seemingly unable to get a decent shot away at David de Gea's net. When Wayne Rooney's shot was parried up by Petr Cech, only for David Luiz to nearly header it back into his own goal, the big Czech goalkeeper kept his side in the tournament.
As it was, from this moment on there seemed to be an unstoppable resurgence from Chelsea, who were saved from a quarter-final exit by second-half super-sub Eden Hazard.
In fact it was United who eventually found themselves holding out for the draw, with De Gea forced into one of his trademark spectacular "foot saves" late into stoppage time.
On April 1, these two giants of the English game will come face to face once again; this time there has to be a winner.
But with home advantage now favouring the London Blues, what can Sir Alex and his men do to ensure the victory?
