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.
Not only a striker but I think Arsenal needs a star player or an experienced player who can lift the team's mentality to be able to perform optimally, Arsenal's problem in the last 2 seasons is not only with the players but also things outside of that that cannot be controlled so that Arsenal always struggles at the end of the competition as if they cannot play as usual when under pressure.
Arsenal seems to have a consistency problem. They start the season really well but they can't continue the season as they want. They need a player who can get the most out of the players, who can take the team forward and lead the team when they are playing. Most of the time, players start losing points one after another in the second half of the season. This is the problem that comes to Arsenal. If they can find a solution to this, there is no reason why they shouldn't finish the season as champions.
