This is how I think we will setup.
Why people on here are saying Clichy has to play to cover Ronaldo I don't know, Ronaldo plays on the left, so it is Zaba he will come up against. Zaba is our best defensive right back if you ask me, Maicon looks short of something from what I saw at Stoke so for me Zaba to come in.
I really don't think we can throw Sergio straight in after being out for a month, packing the mdfeld is my preferred option with Tevez leading the way.
This is how I think Madrid will set up, Higuain to be dropped as his tiredness from playing in the internationals definately showed against Sevilla, the only problem with Madrid playing Benzema is that I dont think he has scored since May.
I am not too sure with Ozil as playing Modric may offer a more experienced role as he has played against us numerous times, Ozil seems to be a faourite under Mourinho from what I have seen though. di Maria had a bit of a shocker against Sevilla in my opinion but I still think he will start this game as he offers lots of pace. Ronaldo is a no brainer.
For me, Madrid's main weakeness is at right back, so putting Silva on that side can expolit that. Kolarov is a question mark, do we play him over Clichy?? I don't know. Clichy is a better defender than Kolarov, but Kolarov has a better cross and can offer a great free kick, something Mancini might possibly look at to get a goal.
Madrid have two great options for left back but with Marcello playing on Saturday, I see Contrao coming in for this.
