Hmm, I'm thinking this will be Madrid's line-up:
-------------------Casillias-------------------------
-Carvajal-------Pepe-----Ramos--------Marcelo-
-------------Kroos------Modric--------------------
-Bale-------------------------------------Isco-----
------------Benzema-------CR7-------------------
The thing is that we play right into the hands of a mid-field like this (especially seen in the first Clasico). However, I feel that there are a few overlooked factors that can affect this match.
1. Ramos and Modric
Everyone automatically assumes that they both are back to their best. But it is important to note that neither of them have had too much match practice after the injury. Granted, Modric did play quite well at Schalke, but right now he's nowhere near his early season form, and we could be lucky because of that.
Ramos, I have a doubt that he'll be anywhere near his best. He just came back from a torn hamstring, that's one of the hardest injuries to shake off and come back to your best. (Messi 2013 a perfect example of the same). These are major Madrid players that we're talking about.
2. Carvajal vs. Neymar
We have to hope that Neymar actually can get the better of him. He was the MOTM last time that we played them, and he was thwarting every effort from the left with heart, and it hurt us a lot. Neymar has the tendency to play in big matches, so hopefully this match-up turns out well for us.
3. Our right vs. their left
This is arguably the biggest factor of the match. Isco had a brilliant game last time out, but at the form Messi is in, he'll have to curb his offense and focus in defense. Alves also needs to be at his best to keep CR7 out of the game. If marked properly, we can make him go MIA. I believe everyone will already know about this.
4. How Mascherano plays. (And the mid-field battle)
He barely offers much in offense apart from some great cross-field balls, but his defensive abilities, covering and leadership abilities. Will be important to deal with cutting off supply to their forward line, as they can be average without proper support.
We also need Iniesta at his best (but he has a tendency to play well in big games, he's slowly but surely getting better), not the prime Iniesta (who was up there with Zidane) but a world-class Iniesta. If he's playing well, we can push Kroos more back and expose him. He's playing well in the circumstances but he's nowhere near becoming the greatest CDM, which we must expose.
Rakitic was asked to play a Xavi-like role in the beginning, but now he has been getting more attacking freedom which is bringing out the best of him. His telepathy with Alves-Messi has been steadily improving. There is a marked improvement from the horror game he had against PSG and he plays well against Madrid.
