Regarding the issue of overhyping, given the extensive discussions about Gyokeres, it might seem reasonable. However, commenting on his performance based solely on one match—especially since it was his debut in a friendly—I believe it is still too early to make such a judgment.
Indeed, Gyokeres is currently attracting a lot of attention due to his performance at Sporting and how clubs are beginning to show interest, coupled with his high transfer fee, which does seem excessive. However, in terms of his performance at Arsenal, I believe he should be given time to adapt before we determine whether he is worth the price tag.
The season hasn't started yet, and Gyokeres has just arrived, so it's not appropriate to force him to perform well immediately because that's clearly not an easy task for a player.
