Sure, any club like that realizes that they have to have some relatively selfless players. You could argue that this problem is why the first Galacticos era of Perez just didn't work, and that they got smarter the second time around. At the same time, they didn't start lifting European Cups until they had both Ronaldo and Bale around, clamoring for playing time and touches. I can't imagine Ramos being the best team player, either.
You could argue that the beginning of Zidane's reign coincides with the culling of a significant amount of ego from that dressing room, which helps to explain the resulting success. Ancelotti could do it prior to that because he's an ego whisperer, but Zidane never could. He's an alpha dog.
