Barbosa served mainly as reserve at Villarreal, but filled in for Viera in several games, most notably in the semifinals of the 2005–06 UEFA Champions League against Arsenal: even though he did not let in any goals in the second leg, the English had won 1–0 in the first match for an eventual qualification.

After one year with Atlas, Barbosa returned to Spain and signed for UD Las Palmas of the second level. He was an undisputed started during his spell in the Canary Islands, never featuring in less than 37 league matches.
On 16 July 2014, Barbosa joined Sevilla FC on a free transfer, penning a two-year deal. On 15 June of the following year, having been demoted to third-choice after the emergence of Sergio Rico, he terminated his contract.
On 9 July 2015, Barbosa returned to Villarreal after agreeing to a two-year deal.
Barbosa was second-choice for the Argentine under-20 team that reached the semifinals of the FIFA World Cup in 2003, eventually finishing in fourth place. He replaced suspended Gustavo Eberto in the round-of-16 game against Egypt, a 2–1 win.
