Ball Posession
Their strong point is maintaining posession (Rising sun arc, chapter 61, page 14).
It is overwhelming according to Xavii (Rising sun arc, chapter 61, page 4).

They were considered the 5th contender for the victory in the olympics by Netherlands' data. (Rising sun arc, chapter 9 page 23)

Blueno was wearing the number 4 against Cameroon, probably a mistake since he wore the number 2 afterwards.

Also, another unknown player was wearing the n°6 before the introduction of Ienista in the semifinals..
