I would play: Bravo - Montoya, Pique, Bartra, Adriano - Rakitic, Xavi, Rafinha - Pedro, Messi, Neymar
1. Bartra has to play.
2. Masche is on 4 yellows so I would not risk him to be suspended against Madrid.
3. I would like Pedro to start because he should be confident for the final stages of the season. He will not start in the big matches but we will need him at some point.
4. That would mean Messi in the center for this match like he played in the beginning of the season. This would help to control the midfield with Raki playing deeper for the first time and more service for Neymar to score who also needs to regain good form.
If Montoya is injured, move Adriano to RB and Mathieu to LB. He should never ever play there against tough opponents but against Eibar it would be absolutely ok.
I only want these chances for this game because of the special situation we are in. Busi is injured, Alves and Alba suspended and Masche has 4 yellow cards. After that this game go back to the usual system with MSN and everything.
