The scoring substitute may be a sign of Arsenal’s greater strength in depth or Mikel Arteta’s capacity to influence games. For Leandro Trossard against Everton and in the Community Shield, Eddie Nketiah at Fulham and Gabriel Jesus against Manchester United.
So far this season, 40 percent of Arsenal’s goals have come from replacements, whether from bringing on Trossard for Gabriel Martinelli or swapping the strikers Jesus and Nketiah for each other. If that statistic probably is not sustainable, Arteta has another kind of impact sub in mind.
