Sanchez joins the Victory on a one-year deal for the upcoming A-League season. 

The 29-year-old moves to Australia after spending most of his playing career in his home country. 

He has won the Copa Libertadores with Estudiantes in 2009, as well as the Argentinean league the following season. 

Sanchez was also part of the Argentina squad that won the 2007 U20 FIFA World Cup, alongside the likes of Sergio Aguero and Angel Di Maria.

Sanchez has spent time in the MLS with Columbus Crew, but most recently was with Temperley - former home of Melbourne City winger Fernando Brandan.

"Mati is a terrific signing for us," said Victory head coach Kevin Muscat.

"His resume speaks for itself. He's been in some very strong teams in Argentina and, more importantly, he's tasted success at club level.

"It's going to be a big season for us with (AFC) Champions League commitments too, so depth is absolutely crucial if we're going to withstand a busy schedule - especially at the back end of the season."

Of the move, Sanchez said: "It is a very exciting opportunity for me.

"I've spent a long time playing in Argentina, so to go on a football adventure to the other side of the world is amazing."

"I would describe myself as a passionate player and a hard working midfielder. I hope the Melbourne Victory fans will enjoy the way I play and I will give 100 percent of my quality to help the team."

"I know Melbourne Victory is a big club, with great fans and I'm looking forward to helping them win more trophies."

Sanchez is Victory's third visa signing, alongside Besart Berisha and Kosta Barbarouses.
