Braña also had a short spell with Argentine club Unión de Santa Fe in 2001.

Braña was a key figure on the Estudiantes team that won its first Argentine League title in 23 years after a 2-1 playoff victory against Boca Juniors to decide the winner of the Apertura 2006 champions.

"El Chapu" won many accolades for his contribution to the championship winning team; he was selected as the third best player of the Apertura 2006 tournament by Argentine sports newspaper Olé.

His typical speed, stamina, and defensive skills in the midfield were key factors in Estudiantes' lifting the continental championship for the first time in 39 years.

Braña eventually decided to stay with Estudiantes, a decision that was rewarded with his first-ever call up to the Argentina national team on 1 September 2009.
