It is not easy for new players to adapt quickly, especially in the Premier League with its intense gameplay --- so Gyökeres must first adjust in order to improve his performance at Arsenal.
It is more difficult for Arsenal to reach the pinnacle of trophies because they always fail at the end, ultimately achieving nothing each season, which is like a curse even though their team is not that bad.
It could be due to the intense competition, making it difficult for Arsenal to win any competition.
Victor Gyökeres has played in England before although not in the English premier league but his experience in England should be able to tell him what to expect.
I think he is a more mature player and he knows the pressure that he will be on, I think he will do well at Arsenal, he is a hungry striker that really want to deliver at the top level and Arsenal has giving him that chance.
Indeed, many players fail to live up to expectations when they move to the Premier League, and there are also quite a few who succeed. Like any other player, Gyokeres will certainly have to go through an adjustment process with his new club, which is certainly not easy. However, I think that if he is not hampered by problems such as injuries, Gyokeres will be able to perform as expected. His experience playing for Swansea City and Coventry City will at least help him understand the culture and dynamics of trophy competition in the Premier League.
Arsenal have been a trophy contender for three consecutive seasons, meaning they have considerable squad depth, and with the signing of Gyokeres, their strength will automatically be further enhanced next season. I think Gyokeres is at the right club, one that can help him achieve his full potential. It's possible Arsenal will be successful in winning trophies next season, now that they have a quality center forward.
