Ruben Amorim apologised to Manchester United fans after a humiliating League Cup defeat to fourth-tier Grimsby Town on Wednesday.
United had fought back from 2-0 down, levelling through Harry Maguire’s 89th-minute header after a poor first-half performance at Blundell Park.
But a marathon penalty shootout ended 12-11 in Grimsby’s favour, with Bryan Mbeumo striking the bar on United’s final kick.
Grimsby, dominant in spells, fully deserved their victory as they outfought and outplayed their Premier League visitors.
Amorim, under pressure since taking over last season, hinted at deeper problems within the team after another poor showing.
