Real Madrid throw away a lot of good players. How many of their 'cast offs' ended up being flops? I can't think of many. Robben, Sneijder, Ozil, Di Maria, Higuain, Samuel, Huntelaar, Garay, Callejon, Xabi Alonso even the likes of Albiol, Sahin, Lass and Negredo did well. Oh and that Morata fella.
Julio Baptista, Robinho, Gago and Van der Vaart were all flops, mostly Brazilians or older players.
