The reigning English league champions showed early on that they are also in the running for the title this season.
Gyökeres’s attacking rival Kai Havertz made it 1-0 after just 15 minutes. Eight minutes later Bukayo Saka made it 2-0.
Norway captain Martin Ødegaard ultimately scored the 3-0 goal early in the second half, and the London side was then able to control the rest of the match.
Viktor Gyökeres, who scored 14 Premier League goals for Arsenal last season, was on the bench for the entire match.
Arsenal became league champions for the first time in 22 years last season.
