Let's take a look after the international match break. There seems to be a 2-week gap for all leagues. The current condition is indeed Real Madrid is losing a lot of players due to injuries. Barcelona may not be as bad as Madrid so they are still quite convincing. But with the current conditions everything can still change, even Barcelona could have difficulties. Currently, there are only 2 teams left that have never lost in the Real Madrid and Atletico Madrid Leagues. But indeed Barcelona is more effective because of its 8 wins and is number 1 in the provisional ranking. It seems that Madrid must take advantage of the January transfer market moment so that they can continue to compete because Madrid is very busy in Lague and Europe.
To make matters worse, Real Madrid are without Vinicius and Thibaut Courtois, and they're also without Andriy Lunin due to an infection. Because the international break can also cause other players who play for their respective countries to suffer injuries, not only for Real Madrid, but for Barcelona as well. About transfers, Real Madrid will definitely make moves in the transfer window, so far there are several names that are their targets, there are Trent Alexander-Arnold from Liverpool and also Jhon Duran from Aston Villa.
In my opinion, I believe Ancelotti does not want Vini Jr to go for the international break, which is why they said he is injured, and I am sure he will be ready for touch matches in the ucl and the league, Carvajal is seriously injured and he will take a long break because the injured is very serious, and Real Madrid has already renewed his contract for two years, so they will look for another best defender if the transfer windows open again in January, because Vasquez can't be only him, they need to look for a replacement for him so that they can continue performing great in the league and champions league, because madrid have tough games this month.
If they rely on Vasquez and he is likely to be injured, Madrid will face significant problems if they do not get another player. Barcelona still has some crucial players who are not injured and will perform admirably, as you will notice because they are performing well and even topping the league standings, whereas Real Madrid will be in trouble if some players do not return before the international break ends. I believe Liverpool is still interested in Alexander-Arnold and will not want to let him go so easy, but he will be a better player for Real Madrid this season if they sign him.
