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.
of course it is a need for the Arsenal team in completing all the existing players, with the attack line will strengthen Arsenal in approaching victory of course that is the main priority even though the function of other players is also important to complement each other. but the Arsenal coach emphasizes defense more than the attack line because of the expensive price to be paid, of course that is the reason to postpone buying the player and that is a consideration for the Arsenal team.
