Injuries will always be a problem that is difficult to solve, especially when there are very important games coming up and we have to be careful not to lose or draw, at most draw, but that is not the idea anymore, there are games that have to be secured, due to this aspect I think that Madrid has many more capable players and that they are very useful for Ancelotti, he should trust them more, I think he needs a little more discipline, to put Mbappé in the centre and that he works out, that is his job, and to leave Vinicius who is doing things well, apart from this, he has the option of bringing back Sergio Ramos who is a bulldog when defending.
Injury most serious problem for all club exactly have right moment when busy schedule matches have to play in Champion League and domestic league. Madrid have list many main players got injury and have one month left or several matches to play before January window transfer opening. Recently Barcelona have bad news due international break after their main player Pedri got injury.
Pedri most crucial players for Barcelona and if bad possibility out for several months later make difficult for Hansi Flick find the right player replacing Pedri position.
I totally agree with you, sometimes these clubs, which for me are the biggest in Europe, continue to maintain their great level even with their players injured, but when you see their benches, both teams can still make a good team, so they have to learn to play with what they have, that's why no player is disposable or sellable because if they run out of material and only depend on the stars, it's very difficult for them to achieve anything, if they depend on the stars, it's something they won't be able to Control, they have to do something, if not go to the preparation schools of each of the clubs.
