Valeri handed Victory armband
The 31-year-old defensive midfielder becomes just the fourth captain of the Victory in its 11-year history, replacing departed Mark Milligan who signed for Baniyas.
Current coach Kevin Muscat was the foundation skipper followed by fellow defender Adrian Leijer.
Victory Chairman Anthony Di Pietro said Valeri possessed all the hallmarks of an outstanding captain, having already displayed elite leadership qualities in his short time with the club.
"I'm delighted to be able to announce Carl as our new captain and I have complete confidence that he will lead the team by example both on and off the pitch," Di Pietro said on Tuesday.
"We have had so many quality leaders in our club over the years and Carl falls into that category without doubt and I look forward to working with him as captain throughout the season."
In his debut season for Melbourne Victory, last year, Valeri played all 29 games and was named Players' Player of the Year.
The Socceroo said he was excited about leading last season’s double-title winners.
"Melbourne Victory is a great club and has had great leaders and I look forward to leading this great team in our quest to defend the title this season," Valeri said.
"It's a great privilege to be named captain and I thank Kevin Muscat and the Board for considering me worthy of such an esteemed role within our football club."
Club stalwart Leigh Broxham has been named as Valeri's deputy.
