Real Madrid absolutely has a lot of quality and there's no doubt about it, it's clear that these players act alone and can manage midfield, defense and attack on their own if they only wanted to, so i don't understand what the problem is, they just have to make more use of the players they have in my opinion.
It's not easy, especially getting these people to play together, if it were easy we would all be very good coaches with other people's money, especially the money of the team owners.
I assure you that making players cooperate is not at all simple, making them play together is even more complex.
