£65 million is too much. His stats this season are more than impressive he has scored 39 goals in 33 matches for Sporting. He would definitely be a great addition to Arsenal and could help a lot, but the question is whether he would have a similar season as he did at Sporting. Either way, i still think £65 million is a lot.
Season 23/24 29 goals and 10 assists, 24/25 39 goals and 7 assists, these are incredible statistics with Sporting, so personally £65 million is a fair price for a striker. Regarding performance, the Portuguese league and the English league are different so it is possible that his performance will not be as good as with Sporting in his first season. The English league is more competitive so it takes adaptation but it must be remembered that Gyokeres is quite experienced playing in that league and besides the club that is interested in him is Arsenal, a club that can manage players well. I hope Arsenal are really serious about getting this player's signature.
