Right manager is tricky to find, if it even exists, if the locker-room is infected by bad habits and an unprofessional attitude from multiple stars. Madrid have run themselves into a new Galactico era with the transfers they made.
This is no longer the Madrid from even 2-3 years ago, let alone the one from 2014-17. Their leaders have left, or retired one by one. The last ones were Modric, Kroos, Benzema, and even Carvajal who is as good as finished.
It happens to every cycle. Madrid managed to tie together two cycles, a great one and a very good one, because they had several leaders that were part in both, but that ended.
There is insufficient leadership in the current team. Likes of Camavinga, Bellingham, that petulant man-child Vinicius, the pampered Mbappe, Rodrygo, not enough leadership and dedication to form the backbone of a new cycle. There is talent, but not nearly enough manhood there.
