Nakhid was more like a classic holding midfielder who supported the creative midfielder (Latas). Both are different types of midfield generals..dictating the tempo and rythm of the game in different ways. I would not class Nakhid as a defensive mid like Emerson, Cambiasso, Makalele or Motta. More of an Edmilson, or Xabi Alonso.
Latas in his prime is more comparable to Riquelme. Few defensive responsibilities, license to roam and the focal point of all attacks...this is not quite Ronaldinho's role (Latas performs more of a Ronaldinho-type role now). At Barca, the Riquelme role is most closely mirrored by Deco, while Xavi (and now Edmilson) perform the Nakhid role (for example). Ronaldinho is basically a withdrawn forward. The closest thing Brazil has to a traditional midfield general right now is Juninho Pernambucano (and he warms the bench). Brazil plays with two holding mids-Emerson and Ze Roberto (or Edmilson, Gilberto Silva, Renato), two withdrawn forwards-Kaka, Ronaldinho (or Robinho) and one 'true' forward - Ronaldo (or Adriano)
