Though there reportedly remains a debate ongoing over the nature and structure of the bonuses included, Mikel Arteta was hoping to have Gyokeres signed in time for Saturday’s departure for their pre-season tour of Asia, along with Chelsea winger Noni Madueke and Valencia centre-back Cristhian Mosquera.

Mikel Arteta often stresses his desire for Arsenal to be “unpredictable” in how they set up - and the signings of Noni Madueke and Viktor Gyokeres will certainly help that. Gyokeres, who scored a remarkable 54 goals in 52 games for Sporting last season, offers an alternative option up front to Gabriel Jesus and Kai Havertz.
