Arsenal made light work of Premier League newcomers Leeds with a 5-0 victory at the Emirates, but the win was overshadowed by fresh injury setbacks ahead of a crucial trip to Liverpool.
Fifteen-year-old Max Dowman made headlines with a late cameo, winning a stoppage-time penalty converted by Gyokeres.
Meanwhile, Kai Havertz’s knee issue, picked up in training, was one factor behind Arsenal’s £60m hijacking of Tottenham’s move for Eberechi Eze.
Christian Norgaard is also yet to feature due to fitness concerns.
Mikel Arteta, who has now overseen more than £1 billion in transfer spending, unveiled Eze to the Emirates crowd before kick-off alongside fellow recruits Noni Madueke, Gyokeres, Martin Zubimendi, Cristhian Mosquera, and Kepa Arrizabalaga.
