Born in Salto, Buenos Aires, Champagne joined San Lorenzo's youth setup in 2001 from hometown side Club Sport Salto. On 9 December 2007 he made his first team – and Primera División – debut, starting in a 4–1 home routing of Gimnasia Jujuy. A backup to Agustín Orion, he only contributed with three appearances during the campaign.
After mainly featuring with the reserves in the following years, Champagne was loaned to Primera B Nacional club Ferro Carril Oeste on 1 July 2010. An undisputed starter for the side, he only missed only one league match during the season.
Returning to Ciclón in 2011, Champagne was initially a backup to Pablo Migliore, but started to feature more regularly after the latter's injury. On 11 July 2012 he moved to Club Olimpo, with Matías Ibáñez moving in the opposite direction on loan.
On 3 January 2017, Champagne was loaned to La Liga side CD Leganés until the end of the season. He made his debut in the category five days later, starting in a 0–2 away loss against Real Betis.
