Barcelona manager Hansi Flick was furious after a substitution nearly left his side with 10 players for a crucial minute during their 2-1 victory over Atletico Madrid at the Riyadh Metropolitano.
With Barcelona protecting their lead and Atletico Madrid pressing for an equaliser, Anthony Gordon took longer than expected to leave the pitch after being replaced by Karim Adeyemi in the 86th minute.
The incident prompted Flick, usually known for his calm demeanour, to demand that the England international move faster. Gordon appeared surprised by the instruction and initially walked slowly towards the touchline, visibly unhappy with the situation.
He then increased his pace and shook hands with Adeyemi before finally leaving the field, while Flick watched in disbelief.
Why the delay mattered
The tension reflected a new rule being enforced this season to prevent teams from wasting time during substitutions.
Under the regulation, a player being replaced must leave the pitch within 10 seconds of the substitution board being shown. If that deadline is missed, the team making the change is temporarily reduced to 10 players.
The replacement must then remain outside the pitch for a full minute before being allowed to enter.
Had Gordon taken any longer, Barcelona would have been forced to play with 10 men for 60 seconds at a stage when Atletico Madrid were seeking the goal that would have levelled the match.
The narrow scoreline kept the contest in the balance until the final whistle. Atletico had initially looked the stronger side after Juliano scored early, but Barcelona recovered and turned the match around to move into a 2-1 lead.
A victory for Atletico Madrid would have had the potential to alter the standings, making the closing stages particularly important for Barcelona.
Rule first used in Real Madrid match
The regulation was first applied in early September during a Champions League match between Real Madrid and Inter Milan, according to Mundo Deportivo.
Vinicius was judged to have taken too long to leave the field in the 87th minute. His replacement, Carreras, was made to wait 60 seconds before entering the game.
Real Madrid protested strongly at the time, with Mourinho among those objecting, but the officials had applied the rule correctly.
Flick’s reaction against Atletico Madrid showed how significant even a short delay can now be. In a match decided by a single goal, 10 seconds were enough to risk leaving Barcelona exposed at a crucial moment.
Barcelona are due to face Villarreal and Getafe in La Liga on 22 November 2026, while Atletico Madrid are also listed for league action on the same date.
