Possible starting 11 line-up Real Madrid:
Diego Lopez; Arbeloa, Sergio Ramos, Pepe, Coentrao; Khedira, Xabi Alonso; Kaka, Özil, Cristiano Ronaldo & Higuaín.
There are however lingering doubts with the starting line-up with these currently mentioned players having stiff competition for their place:
Higuain ( perhaps Benzema? )
Kaka ( perhaps Di Maria?)
Coentrao ( perhaps Marcelo? )
Doesn't the French youngster deserve a start for his brilliant performance & goal against Barça in the home 1º st leg match? Perhaps neither Coentrao or Marcelo will start & Arbeloa will be moved over to the left-back side & Sergio Ramos moved to the right-back side to give room for Varane. Why not?
As you can see plenty of variations available for Mourinho. The final starting 11 will be known 45 mins before kick-off.
