Madrid is in a bad condition after many of their players are injured this time, so it does require them to strengthen the squad in the transfer market later, but I hope that when the transfer market opens later it should not be too late for them as title contenders this season, the injuries of several defenders should be a concern for Ancelotti to strengthen the backline especially this season they have a busy schedule,there are several transfer rumors circulating regarding players who may be brought in in the winter transfer market, some of the names that appear are cambiaso , saliba and also alexander asrnold from liverpool to strengthen their defensive line later, with strong finances and a great reputation as a championship team, of course Real Madrid does has a great attraction for many top european players, So if they manage to bring in these players then I think Madrid problem is over.
Actually getting new players isn't the issue Madrid needs to tackle currently, rather what they really need to tackle currently is a tactic to keep them a float in times when they will be need to hold on till their players come back from injuries just like in this case because the last time i checked, Madrid has got are a really good squad such that they have even a good substitute as well as the first 11 but it appears the injury wave this period did struck hard, except if some players become injury prone and Madrid would want to get them replaced i don't think they need do any transfer currently.
