Alessandro Del Piero, Shinji Ono won't be part of A-League All Stars side to face Manchester United Alessandro Del Piero's absence will be a big loss for the A-League All Stars. ALESSANDRO Del Piero and Shinji Ono won't be part of the A-League All Stars side to take on English giants Manchester United. The two superstars were voted into the team by football fans and an expert panel, but won't be available for the July 20 game at ANZ Stadium. It is understood that Del Piero, who is still in Europe, will fly straight to Japan for Sydney FC's preseason match against J-League side Sagan Tosu on July 24. He's then expected to travel back to Italy where he will continue with his own preseason training. Ono, a key player during the Western Sydney Wanderers' debut season, has returned to preseason training in Sydney earlier than expected. But there are concerns over his match fitness and the club aren't willing to risk losing him as they seek to defend their minor premiership. Alessandro Del Piero (C) in action against Western Sydney Wanderers last season. It's a major blow to the All Stars concept and it is understood Football Federation Australia did everything they could to persuade the duo to take part in the game. Manchester United are undoubtedly the major attraction, but showcasing the best of the A-League is partly what the occasion is about. And Del Piero and Ono, the A-League's highest-profile players, contributed to what was a break-out season for Australian football. But their absence won't detract from the global attention the game will receive. It will be David Moyes' second match in charge of Manchester United and the spotlight will be on Australia during their week-long visit. The Red Devils boast some of the biggest names in European football and won last year's Premier League championship. Wayne Rooney, Ryan Giggs, Nemanja Vidic and Robin Van Persie are among the superstars expected to turn out for the ANZ Stadium blockbuster. Shinji Ono (L) was one of the standouts of last season's surprise package Western Sydney Wanderers. All Stars coach Ange Postecoglou will select the team and there's now an opportunity for more local players to impress on a global stage. Football fans have one last opportunity to watch the All Stars take on Manchester United live at ANZ Stadium. UNICEF Australia has launched an online competition giving five fans a chance to win double passes to the sold-out match.
