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.
Personally, I am also surprised by the situation that befell the Real Madrid players, but what is clear is that it is very difficult to research what the cause is, which is why Real Madrid players are hit by so many injuries and if you look at it now, of course there are a lot of Real Madrid players who are injured. Because currently many players are injured, of course this sometimes makes Real Madrid fans a little nervous.
However, what you say is true because there are many star players at Real Madrid who are of course busy in international matches and also defending their clubs such as in the UCL domestic league and so on. Of course this will create the potential for these players to suffer injuries. but what is certain is that this is the challenge for star players who of course must be able to really maintain their performance, health conditions and so on.
Of course, in this case Ancelotti must really be able to look after the Real Madrid players. and of course this is the first season for Mbappe and Real Madrid have wanted this star player for a long time and indeed, if for example Real Madrid don't become champions in the UCL or in other leagues, of course many Real Madrid fans will be disappointed and of course we'll see what happens next. But of course, no matter what, Real Madrid will still be the favorite team to win the UCL title and others.
