I think I know why Arsenal seem slow to sign new players, especially for the striker position, because they are not a team that has a big budget like Man City and Liverpool, so Arteta must be wise in making decisions. Gyokeres is indeed rumored to be the main target, but for some reason, Sporting CP suddenly wanted a higher price, and that made Arsenal revise their wishes, and there is even talk that Arsenal would now prefer to recruit Benjamin Sesko.
One of the things that made Arsenal fail was the weakness of their attacking line, so it will be interesting to see which striker Arsenal will sign.
If they know that the weakness is in the attack line, then buying a player at a slightly higher price is not a problem as long as the player is a team need. In the previous transfer market, Arsenal bought players at high prices and this should be able to be done again to bring in Gyokeres and even if in the end Arsenal decides to bring in Benjamin Sesko, can the player be a solution to Arsenal's weak attack line?
We know Arsenal is not like Man City or Liverpool but in the last two seasons Arsenal has started to dare to spend a lot of money to buy a number of players who are considered suitable by the coach. But the current transfer market is so slow and seems to have no desire to evaluate the attack line so that the players needed have not been bought.
