[AYUDA] Formaciones

Heya, everyone,

I'm an argentinean football fan and following the Torneo Apertura, I got a lil confused about how some of the best team plays. I hope you can help me explaining how they play.

Vélez is the one who intrigues me more. Especially this player who seemes to be very good - S. Sena. how does he play? As right-defender or midfielder? What about Ocampo? And Bustamante, left-defender perhaps? Fortin plays with three defenders sometimes, doesnt it?

Is Boca still playin like the first semester, with three players behind the playmaker, now Gracian?

About Estudiantes, where does Benítez plays? He seemes to be amazing. But as left midfielder, isnt it? And Piatti?

Is Tula playin as left defender in San Lorenzo?

River formation is similar to Boca's one when Ortega is playin in the attack, isnt it? Buanannote playin Riquelme role.

Sorry for so many questions, buddies.

Feel free to answer in spanish. It's ok.

Abrazan!
