This is what is worried about every big club that spends money to buy players but the results obtained are still not so satisfactory that it causes feelings of disappointment and loss, this is an important task for management and coaches who must continue to provide full support to players who have just entered to be able to contribute to the maximum, because if it is still like that then the only way is to sell the player again.
You are right, reflecting on last season we have seen players who are bought at high prices actually become an obstacle for the club itself. So it's no wonder that club managers are now evaluating the performance of players from every purchase so as not to give up disappointment. For now, buying at an expensive price does not guarantee that the quality of the players can be comparable. Even we see giant clubs do a lot of careful consideration. Hopefully that is an improvement in terms of the quality of the new players.
