Only Casemiro plays as the defensive midfielder, while others are ball jugglers. Liverpool uses double defensive midfielders that can conquer the two the two Real Madrid ball jugglers and they would still be chanced to throw the counter passes that they are good at, most especially Thiago. Thiago is not just a defensive midfielder, he jug ball as well, he plays in a way that would result to goal for them, both defensive and jugging while Real Madrid have only attackers. They would get to win themselves in one of the two, either in the midfield or defense line.
The only way I know that Real Madrid can get to handle Liverpool is not to let their two wing back operate or give them chance to think at all, talk less of throwing ball to their midfielders and from their midfielders to their attackers. If Liverpool attackers handle the defense line of Real Madrid, they would make them to create chance themselves if at all they don't want to create the chance at all before. Sadio Mané dribbles and Mohammed Salah dribbles as well, Salah have permanent place he plays but Mane can play anywhere in the front.
I think only Vinicius Junior can make Alexander Anold stay at the back, not to attack too much like he always do, but I doubt he can stop him from throwing passes, if he stay home to avoid Real Madrid counter attack, then he can put ball to his midfielders feet and from there, they would use the ball for something reasonable. Ferbinho can attack and bring goal if Liverpool is badly in need of goals and back in the days that Real Madrid have headers at the back, they didn't have Sergio Ramos again, but Liverpool have Van Dijk.
I think Liverpool have styles of play more than Real Madrid but it may not be like that on Saturday evening, they are both going on a neutral ground where it's not non of them's field and it's the number number of fans that would follow them. We know Liverpool fans as fans that are always noisy and with their noise, they help their club so do so Real Madrid fans, they have noise as well but this is a neutral ground that their noises may not be useful because it's not their home.
