Arsenal secured a dramatic 1–0 away victory over Sporting CP in the first leg of their UEFA Champions League quarter-final, thanks to a stoppage-time goal from Kai Havertz after a decisive impact from substitutes. For much of the match at Estádio José Alvalade, Arsenal struggled to break down Sporting’s defensive block and looked likely to settle for a stalemate. However, the late introduction of Gabriel Martinelli and Havertz transformed the game. In stoppage time, Martinelli delivered a precise cross that Havertz converted from close range, giving Arsenal a crucial advantage heading into the second leg.
