Son opened his 2019–20 account on 14 September 2019 by scoring two goals against Crystal Palace in the Premier League with a final result of 4–0. On 21 October, Son was named in the 30-man shortlist for the 2019 Ballon d'Or. On 3 November, Son was sent off during a 1–1 draw with Everton after sliding into André Gomes from behind, causing him to fall awkwardly and suffer a severe ankle injury. The injury prompted great concern and anguish from the players and supporters; Son was visibly highly distressed by the incident. Following a red card for a challenge on Gomes, Son also received suspension for three Premier League games. However, many professionals including former Everton player Kevin Kilbane expressed criticism of the red card decision, and Tottenham made an appeal to the Football Association against the dismissal. The FA accepted the appeal and Son's red card was rescinded on 5 November. Three days after this incident, in a 4–0 Champions League away game to Red Star Belgrade, in which Son scored a brace, rather than celebrating his first goal, he apologised to the camera for what happened at Goodison Park.
