The prestige of the inaugural A-League All Stars match is set to take a hit, with Alessandro Del Piero and Shinji Ono expected to miss the game against Manchester United this month.
Sydney FC's Italian veteran Del Piero and Western Sydney Wanderers' Japanese marquee Ono are arguably the two biggest names to grace the competition and were a driving force behind the popularity and success of the 2012/13 campaign.
But according to reports appearing in The Daily Telegraph, neither player will be available to line up against United at Sydney's ANZ Stadium on July 20.
Currently in Europe, Del Piero, 38, will reportedly not re-join his Sydney team-mates until their friendly against Sagan Tosu in Japan on July 24.
And it is alleged the Wanderers will not risk making Ono available so early in the 33-year-old's carefully structured pre-season training program.
Several other players voted into the All Stars squad by supporters will also be unavailable due to a combination of retirement, transfers overseas and international commitments.
The match against the All Stars, coached by Melbourne Victory's Ange Postecoglou, will be David Moyes' first in charge of Manchester United since he succeeded Alex Ferguson at the end of last season.
