A comeback in football refers to a situation where a team that is losing a match manages to score enough goals to equalize or surpass their opponent's score, thereby turning the game around and securing a victory or draw.
Comnbacks often involve a significant change in the momentum of the match and requires a combination of skill, strategy, and mental fortitude from the team that is behind.
A notable example of such a comeback is Charlton Athletic 7-6 Huddersfield Town match on 21 December 1957. With 27 minutes left, Charlton were losing 5-1 and down to ten men. However, they scored six more goals to win 7-6.
