I agree with you. In the past few seasons, we have seen Arsenal buy players at high prices, but we do not see the expected performance from the players. Arsenal must be careful about buying players and at the same time be smart. Otherwise, even after spending a lot of money, the squad will not improve.
Coach Arteta is experienced. Arteta must find the weaknesses of his squad. At the same time, he must find players who are suitable for Arteta's match strategy. Otherwise, even after spending a lot of money, Arsenal's performance will not improve. But personally, I think Arsenal should strengthen their bench team more now if they want to continue their good performance.
I totally agree with you about how Arsenal buys players. Team has spent a lot of money on new players in last few years but they have not always played as well as expected. To really make team stronger Arsenal needs to be smarter about who they buy. They should choose players who fit with coach plan. Also as you said they need to make their backup players stronger. This will help them keep playing well even when their best players get hurt or are too tired. If Arsenal can do this they will be able to reach their full potential and have long term success.
Sure. Arsenal bought players and spent a lot of money, but they are still finding it difficult to get what they want at the end of the season; however, to me this is not really from the players. I think the coach is the one who plans how these players will play their match, so for this he should be the one to plan what will suit these players and get what they want.
Furthermore, you are right; they should know the kind of players they buy. I even think Arsenal is really confused, or I should say Arteta is kind of confused; even with his experience, he’s still finding it difficult to make this team achieve what they want. At the end of the day, they are not keeping their consistency for long. And that is what is affecting the squad.
