Fleetwood 1-1 Arsenal (5-3 on pens, League Cup, 2026)

Fleetwood Town celebrated the biggest victory in the club's history as they stunned Champions League finalists Arsenal to reach the EFL Cup quarter-finals at Highbury Stadium.

The League Two club stunned the visitors when Aaron Loupalo-Bi gave Fleetwood, who sat 19th in English football's fourth tier, a 21st-minute lead.

Viktor Gyokeres pulled Arsenal level after the break - but they could not kick-on and were reduced to 10-men in the 86th minute when teenager Max Dowman kicked out following a challenge by Harrison Neal.

In the shootout, Fleetwood goalkeeper Jay Lynch saved Bruno Guimaraes' spot kick before Conor Haughey scored the winning penalty to spark scenes of ecstasy on the pitch and in the stands.

Grimsby 2-2 Man Utd (12-11 on pens, League Cup, 2025)

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.

But an incredible shootout followed, 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.

Plymouth 1-0 Liverpool (FA Cup, 2025)

Arne Slot made 10 changes to his Liverpool side after they had won an EFL Cup semi-final in their previous game and the Reds were made to pay.

Eight minutes after the interval, the Pilgrims were awarded a penalty after Harvey Elliott's handball and Ryan Hardie drilled home from the spot in emphatic fashion.

Hardie almost added a second shortly afterwards when his shot was turned on to the post by Liverpool keeper Caoimhin Kelleher.

The bottom club in the Championship held on, with Conor Hazard making crucial late saves, to beat a team who would go on to win the Premier League title.

Chelsea 2-4 Bradford City (FA Cup, 2015)

Bradford ranked 49 places below their opponents as they travelled to Stamford Bridge to take on Chelsea, who at that point were top of the Premier League.

Gary Cahill and Ramires netted to put the hosts 2-0 up and give Chelsea firm control of the fourth-round tie.

Bradford had other ideas, though, as Jon Stead pulled one back before Filipe Morais side-footed in an equaliser.

Andy Halliday then blasted the Bantams ahead before Mark Yeats slotted a fourth to inflict a crushing defeat on Jose Mourinho's side.

Oldham 3-2 Liverpool (FA Cup, 2013)

Premier League giants Liverpool had ample strength at Boundary Park, with the likes of Luis Suarez, Raheem Sterling and Daniel Sturridge all starting.

League One hosts Oldham were in the midst of financial problems but produced a spirited display against the odds, with Matt Smith nodding in a Youssouf M'Changama cross to open the scoring.

Suarez levelled, but Smith soon took advantage of an error from Liverpool goalkeeper Brad Jones before Reece Wabara netted a back-post header to give the Latics a 3-1 lead.

Joe Allen volleyed home to pull one back and Liverpool brought on Steven Gerrard, but it was not enough to avoid defeat.

Bradford City 1-1 Arsenal (3-2 on pens, League Cup, 2012)

A fourth-tier side against Premier League opposition in the quarter-finals of the league cup - Arsenal were clear favourites.

Bradford had already caused an upset in the tournament, beating Wigan on penalties in the round before.

Up for a fight at home to Arsene Wenger's Gunners, Garry Thompson volleyed the Bantams ahead before Thomas Vermaelen headed home a Santi Cazorla cross with just two minutes of normal time remaining.

Just as Mbeumo missed the decisive kick for United against Grimsby after scoring in normal time, the same happened for Vermaelen here as Bradford prevailed 3-2 on spot-kicks.
