The recent match between Clyde and The Spartans serves as a stark reminder of how quickly fortunes can change in football. Leading 3-0 after an hour, Logan Dunachie's red card saw Clyde squander their lead, ultimately drawing 3-3. This incident raises the question of the most significant collapses following a red card in football history.

Historically, several teams have struggled after losing a player:

• In the 2017-18 Premier League season, Liverpool was down 1-0 to Manchester City when Sadio Mané received a red card, leading to a humiliating 5-0 loss.
• Southampton faced a similar fate in 2019 against Leicester, losing 9-0 after Ryan Bertrand was sent off early in the match.
• VVV-Venlo suffered a staggering 13-0 defeat to Ajax after Christian Kum's dismissal.

However, some of the most painful red cards occurred when teams lost leads. In 1991-92, Foggia was 4-1 up against Atalanta when Dan Petrescu was sent off, resulting in a dramatic 4-4 draw.

An equally memorable match occurred in 2010-11 when Arsenal led 4-0 against Newcastle before Abou Diaby was sent off. The Gunners collapsed, with Joey Barton scoring twice and Cheick Tioté netting a last-minute equalizer for a 4-4 finish.

More recently, in December 2021, Venezia blew a 3-1 lead against Verona after Pietro Ceccaroni's red card, leading to a famous comeback from the opponents.

These instances highlight the direct impact a single red card can have on a team's performance, often leading to dramatic and unforgettable outcomes in football.
