However, Del Piero - arguably the biggest signing in A-League history - only made it to the bench.
Melbourne Victory coach Kevin Muscat was rewarded for his career as a fierce defender by receiving more votes than any other player and being named the team's skipper.
His former mentor - two-time championship-winning coach and Socceroos boss Ange Postecoglou - was voted coach of the decade.
"To be nominated by my peers, both past and present, is extremely humbling and something that I take great pride in," Muscat said.
"I would like to thank Melbourne Victory for giving me the opportunity to return to Australia back in 2005. I have nothing but respect for everyone who has been associated with the club and I look forward to what the future holds."
PFA chief executive Adam Vivian hailed the team and said all of them had made an enormous contribution to the success of the A-League.
"To have won 25 A-League championships between them highlights just how big their contribution has been, and the impact they have made," he said.
"They, and their peers, have worked tirelessly over the past 10 seasons to build a competition that offered very few guarantees into one that is now one of the biggest success stories of Australian sport for the past 10 years."
Selected by the PFA's A-League members past and present, players were asked to vote for their starting 11 in a 4-3-3 formation, along with five substitutes, a coach and referee of the decade.
