Fleetwood Town achieved one of the biggest cup upsets in history, defeating Premier League champions Arsenal 5-3 in a penalty shootout to reach the EFL Cup quarter-finals. The League Two side led through Aaron Loupalo-Bi before Viktor Gyokeres equalised for Arsenal, who were reduced to 10 men when Max Dowman was sent off in the 86th minute. Goalkeeper Jay Lynch saved Bruno Guimaraes' spot kick, and Conor Haughey scored the decisive penalty.
BBC Sport examines this and other historic shocks, including Grimsby's penalty drama against Manchester United, Plymouth's FA Cup win over Liverpool, Chelsea's 2015 FA Cup defeat to Bradford City, and Oldham's 2013 victory over Liverpool.
