It's now official. Barcelona's Carles Puyol has won his fitness race to start against Real Madrid, while the capital side have rung the changes in the middle of the pitch.
The visitors' typical formation sees no change, but the return of Puyol to the line-up means that Sergio Busquets can take his typical defensive midfield role.
Meanwhile, for the hosts, Pepe is set to reprise the defensive midfield role that he played last week against Athletic Bilbao. Coach Jose Mourinho is counting on the expertise in that position gained through the defender's time with the Portuguese national team.
Up front the three-pronged attack sees Karim Benzema lead the line, with Emmanuel Adebayor's bid to start seemingly failing. Barcelona opt for a typical forward three of Pedro, Lionel Messi and David Villa, with the Argentine likely to come face to face with Pepe when he comes deep.
Pepe's start means that Mesut Ozil is restricted to the bench for a match that sees Madrid switch to an unfamiliar 4-3-3 as they attempt to change their ways after the 5-0 Camp Nou defeat in 2010.
