Fleetwood Town's victory over Arsenal is one of the biggest upsets in League Cup history, with the Premier League champions entering the contest with just one loss across 11 league and UEFA Champions League fixtures this season. The match was played between the reigning Premier League champions and a League One team, with Fleetwood Town's Jay Lynch denying Bruno Guimarães' penalty attempt to send the game to penalties.

Fleetwood Town fell behind in the 21st minute when Aaron Loupalo-Bi scored, but Viktor Gyökeres pulled the visitors back level five minutes into the second stanza. The Premier League giants couldn't find a winner inside 90 minutes, forcing the game to penalties. Fleetwood Town's Jay Lynch denied Bruno Guimarães' penalty attempt, and Conor Haughey then smashed home the winning penalty to spark a pitch invasion.

Fleetwood boss Matt Lawlor admitted that his team hadn't practiced penalties, saying "I'm not gonna sit here and blag you and say we've done some meticulous penalties; we haven't practiced." Despite this, they were able to overcome the Premier League giants and secure a historic victory.

Fleetwood Town's win slots comfortably into ESPN's stockpile of giant killings in the League Cup, joining other notable upsets such as Grimsby Town's defeat of Manchester United in 2025 and Bradford City's defeat of Arsenal in 2012.
