Tottenham Hotspur made an unprecedented early substitution in their Champions League last-16 tie against Atletico Madrid, replacing goalkeeper Antonin Kinsky just 17 minutes into the match. The 22-year-old Czech Republic international conceded three goals in the opening quarter-hour, including an error that led to Marcos Llorente's sixth-minute opener and a giveaway that allowed Julian Alvarez to score in the 15th minute.

Interim manager Igor Tudor acted swiftly, bringing on Guglielmo Vicario, who had been dropped for poor performances. The Italian keeper conceded again five minutes after entering as Atletico raced to a 4-0 lead by the 22nd minute. Pedro Porro's goal before halftime reduced the deficit, but Tottenham faced an uphill battle after the disastrous start.

Kinsky, signed from Slavia Prague for £12.5m in January 2025, endured a nightmare debut in such a high-profile fixture. His first mistake came from a slip that gifted Llorente the opening goal, followed by being caught in possession for Atletico's third. The keeper was visibly distraught, with his head in his hands before being substituted less than two minutes after Alvarez's goal.
