BILBAO, Spain -- It took just 36 seconds for Gabriel Martinelli to justify Mikel Arteta's belief that Arsenal now possess the squad to win the UEFA Champions League. After 70 minutes of toil against Athletic Club in Spain, Martinelli's instant impact as a match-winning substitute proved that Arteta now has game-changers on and off the pitch.
Martinelli's goal, 36 seconds after replacing Eberechi Eze, came from a pass by Leandro Trossard, who had only entered the game himself six minutes earlier in place of Viktor Gyökeres.
