Midfielders:
Toni Kroos has been controlling the midfield for Real Madrid in all their big matches, and Zidane would want him to do the same today. With Barcelona set to play Iniesta and Rakitic, the German will have a tough time keeping hold of the ball.
Luka Modric has lost his pace but is still very efficient in the midfield for the Blancos. He too will find it challenging and with his countryman, Rakitic playing for the opponents, it's going to be fun to watch them battle it out in the middle.
Casemiro will be the 3rd midfielder in Zidane's 4-3-3 formation tonight. The Brazilian has been in top form this season but was responsible for Bayern Munich's penalty in the 2nd leg. He was reckless and was lucky to be on the pitch.
