I have absolutely no clue why Real Madrid keeps getting these injuries, surely there must be something about the training they are doing, but also they have world stars, who all play for international games, so between league games, UCL, cup, club world cup, and then back to league, these players play like 60+ games a season which makes them injury prone and tired and the fatigue makes them injured easier.
Whatever is the reason, they have to find the problem at the root cause and fix it very quickly, because they can't afford to have a bad season. It's their first year with Mbappe, and fans are expecting a lot from them this season, if they fail to get anything, then it is going to be pretty tough to tell fans to calm down and wait for another year.
Maybe it's true that the training process given to their players is heavy enough to make them quickly fatigue and their performance decreases and then injured, in view of the number of injuries it is possible that this is in the training process they do, or some people are given a different and very heavy way of training to improve their abilities.
Calm down guys, it's still early in the season, there's still plenty of time for them to catch up, I think Ancelotti must have found the answer in dealing with this problem, because as far as I know Real Madrid will not go down far despite these circumstances, they just need time to be able to make fans proud of them again.
