The cases of Hazards and Musondas are clear, the less prominent ones were brought to accomodate the real targets. The Belgian, Spanish and Brazilian are probably both, to create harmony and sense of belonging while still profiting from their talents. With those 3 nations it's easy, because they have many good players and it makes sense to acquire a handful of same nation players, instead of an "outsider" with same kind of talent and resale value. This, I suspect, is one of the reasons why we are watching Azpilicueta more closely, instead of Van Der Wiel, Debuchy or Piszcek, who would be outsiders. We were also close to signing Maicon, a Brazilian.
