Unbelievable scenes at Blundell Park as the Red Devils crashed out of the Carabao Cup to League Two’s Mariners! United needed late heroics from Mbeumo and Slabhead to force penalties, but Onana’s nightmare in goal and a missed spot-kick from Cunha sealed the upset. Grimsby’s keeper Pym was the hero, and both goalies even scored in the shootout! This one’s a new low for United—fans, where do we go from here? #Sports #Soccer #ManUnited
