5) Sergio Aguero (Manchester City)
Linked many times with both clubs, Manchester City striker Sergio Aguero is a world class finisher and would not be out of place among the marquee signings at either the Bernabeu or the Nou Camp.
6) Marco Reus (Borussia Dortmund)
Another world class talent linked with both Real and Barca in recent times, Borussia Dortmund forward Marco Reus would be a superb buy for the La Liga giants.
