Italian star Alessandro Del Piero has been a standout so far in his A-League career with Sydney, but the former Juventus playmaker says his best is still yet to come.

Del Piero, 37, has impressed in all three games he has played for Sydney FC this season, scoring two goals including the match-winning goal in last Saturday's Sydney derby, which followed a scintillating freekick in his home debut against Newcastle.The Juventus great will play his 800th professional match, including club and international games, against Perth Glory at Sydney's ANZ Stadium on Sunday and says he expects his performances to only get better with every game."I'm not 100 per cent, definitely," Del Piero said. "I'm feeling good because I'm training every day and this is important. After five weeks, I think I'm happy to be in this condition and hope to do my best in two or three weeks. I know my teammates more day by day and we won our first game and nice news happen so it's a good start."Del Piero spent 19 seasons with Juventus, two with Padova early in his career and played 91 internationals for Italy, which included a World Cup win in 2006.Del Piero stated he never dreamt of playing so many games, and that he would never have guessed he would mark the special occasion whilst playing in Australia. "If I'm honest, no, but I'm happy it will happen here," Del Piero said. "It (800 games) is a long time. I'm happy to be here and I broke a lot of records in Italy. Now I start here."When I played my first game, I was really happy - it's enough. I was 18 and I didn't know what would happen with the future.I had a lot of dreams and a lot of them have happened and I'm lucky for that."Del Piero won a controversial penalty in the win over the Wanderers at Parramatta Stadium but denied suggestions by Western Sydney goalkeeper Ante Covic he was receiving favourable treatment from referees because of his status."Absolutely not. For sure, no. Unfortunately, not". Del Piero said he was still coming to grips with the physical nature of the league and was looking to continue his good form against last years runners up, Perth Glory."They are a very good team, not only physical but technical, and that's probably why they have six points now. I have to do my best. I'm not big so I have to do something else but I have time in training to understand what is best for the team," Del Piero said.
