Unfortunately, this is not surprising - last season was too long for Real Madrid players, considering that modern footballers are already playing at the limit of their capabilities, such abnormal loads make themselves felt. It is clear why Perez wants to assemble almost two squads - for top clubs this is a necessity and not a whim. If we are to be positive, we must remember that last season for Real also started with a large number of injuries, but in the end everything worked out and the season turned out to be excellent.
Real Madrid actually have the capacity to actually build a squad with multi players for each position and the players will be high class players but the major thing is the breaking of the wage structure set by the FIFA and the other bodies, more so the players in question would also want to play more football and wouldn’t want to sit on the bench all the time so it is not usually possible like that to have an all round star studded squad.
I will say Real Madrid actually gambled when they didn’t sign a new center back before the close of transfer window. They had the young academy graduates who picked up injury right before the season started. Carlo Ancelloti was with the intention of deploying Tchouameni to the role but him and Eder Militao now are out injured which is a scary thing for this Madrid team now. Maybe they could get anyone of them back before then or result back to the academy for a player at that position
