Watford suffered the upset at Tranmere but
Manchester United will have felt a little queasy too. Prenton Park awaits Ole Gunnar Solskjær on Sunday and a trip to a weakened
Premier League opponent may have been preferable to visiting a bog of a pitch plus a team languishing 21st in League One with nothing to lose. On this evidence Micky Mellon’s side will relish the chance to claim another top-flight scalp.

Tranmere’s substitute Paul Mullin scored the extra-time winner that secured a lucrative date with United in the fourth round. The striker, whose late goal completed Rovers’ comeback from three goals down at Vicarage Road, headed home from close range after the impressive Corey Blackett-Taylor glanced on a cross from substitute Harvey Gilmour. Tranmere, ahead through Manny Monthé but pegged back in normal time by Kaylen Hinds’s equaliser, should have won inside 90 minutes against a makeshift Watford team who laboured throughout. The victors will not mind going the extra mile for the opportunity to increase Solskjær’s torment, however.
