So it is no longer a thing to contemplate on and as a matter of fact, it has become proven that the more money a club spend during the transfer market determines how successful in the next season because there will be able to engage the best players for the next season.
Hopefully, they learn from the transfer mistakes that have been made in the past. They failed with the transfer of star players, such as Eden Hazard, James Rodriguez and Luca Jovic. They could not play optimally with Madrid and failed. But it's not all money, that's not the case for any of Chelsea's EPL clubs. They seem to spend the most money for the winter transfer window. But a shopping even they didn't get better.
Not just how much a club spends during the transfer market but also how competent the coach is to manage the star players gotten during the transfer market determine how far the club will go fo a particular season. Madrid didn't get the best from their last season transfer window sake of injury. The outcome might not be classified as a failed transfer because if not for injury we would have seen the best of their abilities
