Manchester United and Wolverhampton Wanderers will have to do it all again in the FA Cup after the Premier League pair played out a goalless draw at Molineux.
There were changes aplenty following a hectic festive period for both clubs and neither could get a foothold in a fairly drab first-half.
Sergio Romero produced one fine save to deny Matt Doherty but that was the only event of note.
The second period saw chances for both sides, with Juan Mata first seeing a free-kick fly just inches wide before second-half substitute Marcus Rashford hitting the bar with a deflected effort.
Doherty had a goal disallowed for handball, while Raúl Jiménez hit the post as the game drew to a conclusion.
The replay will suit neither manager, as both are already having to juggle their squads due to Europa League commitments and United are in League Cup action on Tuesday, but neither side can feel unlucky not to win following what wasn’t a great advertisement for the competition.
