An upset as astonishing for its manner as it was for its proportions. Grimsby Town, a League Two side, beat top-flight Manchester United.

Not only did they win, but they were 2-0 up after 30 minutes following goals from Charles Vernam and Tyrell Warren.

The visitors pulled one back through Bryan Mbeumo with 15 minutes to go and United looked like they might squeeze through when Harry Maguire went on to level in the 89th minute.

It went to penalties and what ensued was an incredible shootout, with Clarke Oduor for Grimsby and Matheus Cunha for Manchester United missing the only penalties as each side's 11 took one.

The players then went again and, after Darragh Burns scored to make it 12-11, Mbeumo struck his second spot-kick against the crossbar.

Sheffield Wednesday make 10 changes to the team that lost 3-0 at home to Bristol City on Saturday and remain winless in the Championship this season. Goalkeeper Ethan Horvath is the only player to retain his place.

Grimsby Town boss Dave Artell has made two alterations from the XI that started the 1-1 draw with Cambridge in League Two on Saturday. Forward Justin Amaluzor came off the bench to score the injury-time equaliser against the U's and is rewarded with a place in the starting line-up and defender Reece Staunton also comes in.

Sheffield Wednesday XI: Horvath, Emery, Weaver, McGhee, Kobacki, Fusire, Thornton, Shipston, Johnson, Lowe, Brown.

Subs: Stretch, Palmer, Otegbayo, Alao, Bannan, Grainger, McNeil, Onukwuli, Ugbo.

Grimsby XI: Pym, Staunton, McJannet, Warren, Rodgers, McEachran, Green, Khouri, Amaluzor, Vernam, Kabia.

Subs: Casper, Eccleston, Oduor, Sweeney, Walker, Burns, Borwn, Turi, Soonsup-Bell
