I completely agree that financial power must also be utilized properly. Because even though they get good financial support, if it turns out that some of the players brought in fail to make a good contribution to the team then it will be a failed transfer which could ultimately result in the club incurring losses. .
This is also the role of a coach or football manager in this case when choosing which players to buy. Because, there are such things as purchases that are successful and not, purchases that are effective and not, and purchases that are worth it and not.
And it does happen, there are several coaches or football managers who make large-scale purchases with quite high fees but fail to become successful. Several things happen in big clubs. For this reason, every club certainly has an evaluation of this matter, especially regarding the plans of their football manager.
But in Serie A clubs I rarely hear of clubs spending excessively on an expensive player. So that unnecessary financial problems should always be avoided.
Yes, you could say that, in Serie A, it seems quite rare to see or know the extraordinary performance of a player so far. Usually, it will become a club in the Premier League (quite a lot of clubs) or in La Liga (like Real Madrid and Barcelona)
