Muller made his mark on Argentine Rugby when he was selected in the Argentina U20s squad for the 2013 U20 World Championship.
The 90kg winger spent three seasons with the Argentina 7s side racking up 42 appearances and he represented his country at the Rio Olympic Games.
He joined Toulon ahead of the 2016/17 season where he played 11 games and scored 4 tries.
In June 2017 Oyonnax confirmed the loan deal of Muller for the 2017/18 Top 14 season from Toulon.
He signed a contract extension with Brive that will see him stay at the French club at least until the end of the 2020-21 season.
