Which Real Madrid are you referring to? Do you mean the one that scored 6/6 in the Champions League group and 21/24 in La Liga? Well I guess you must be right and Ancelotti can't sleep well because everything is in shambles. The offense is doing well, the defense is doing well, Vinicius Junior is healthy and back on the pitch, Bellingham is developing into a world star.
Perhaps you could more precisely pin down what the issues are that you see and what you think Ancelotti is so concerned about that he would describe the club's situation as not very good to use your words.
I think Yurkov too often expresses inaccurate opinions in football discussions, I'm not sure what his motive is but it's good not to get emotional because it's nothing. He seems to understand football, but in terms of analysis and facts he is too bad.
Real Madrid has adapted to the depth of its squad this season. They don't seem to have many problems winning matches, but that doesn't mean they are perfect without any flaws. Real Madrid's defense has been hampered by injuries, while they also lack quality strikers when they need them in big matches. If someone is worried about Real Madrid against Atletico Madrid, then I would also think that they would also be worried about Real Madrid against Barcelona.
Not really getting emotional about him, but I think if people are trying to post for whatever matter they are doing it, the least you can do is to create your post such that it has a least minimum of substance for the reader. If it doesn't, it's crap to just spam. It should at least make some sense and in sports be up to date. But whatever, may he post his way through the forum in whatever way he deems right for him.
In regards to Real Madrid, better is always an option and if they had a few free wishes for their team, they would probably add a striker as you said and strengthen the defense. But if you see Real Madrid right now as they are, do you think they are competitive enough to win their games in the knockout stage of the Champions League as well? I think so, but the only team that would really cause them to have problems and lose dominance entirely during a game is Manchester City. All other teams have their own issues. And as you can see, Manchester City isn't perfect either. Very susceptible do counter attacks as against Leipzig and that game could have ended in a draw. But Real Madrid isn't Leipzig. I think despite the fact that some positions could be improved, I thought they would have more problems without a striker but if Bellingham can keep filling that gap only half as good as he has been doing recently, in my opinion they have chances to win it all. I was a lot more pessimistic pre-season. But there is risk to their setup because what if Bellingham gets an injury and misses two full months?
