Aside from Carvajal who recently got an out-of-the-season injury over the weekend, no other Real Madrid player is injured. Real Madrid just employed those tactics to keep them from travelling for the international break so they will be well-rested.
Mbappe did not go to France, they claimed he was not fit, but he played against Lille and started against Villareal. Vinicius and Militao didn't go to Brazil either.
I can't blame Real Madrid for using these antics, the players need to be protected since we're entering the heat of the season. They need to refresh and get themselves back. the problem is, nobody cares because its Real Madrid, if it was another club, the media would have come hard on them. They did the same thing in the last international break and they're doing it again now.
Everything traced back to Carlo Ancelotti because he's the main man for the managerial role in Santiago Bernabéu. Los Blancos understands their craving desperate hunger for major titles this season and looking forward to it would be huge chance for the new faces in the club. Real Madrid players are probably switching lanes to be unavailable for country call up duties this week. Why? It's simple, when these players go for international duty call-up, most of them are sustained with minor or major injuries. The international break is here, time for these clubs to have rest because the top competitive race in the club's league is totally frustrating.
Carvajal who happens to be one of the oldest players in Real Madrid, he defends magnificently. He have been defensive this season, he knows the grassroots of the club and have delivered stellar performance on the pitch. The Spaniard is currently been injured and its recorded to br out for 7/8 months. Real Madrid squad have good players with possible enchanced mentality to elevate the performance of the club.
