If he lost weight, he lost muscle mass. Del Piero was all but fat in the WC. You could see his ribs FFS. I'm more worried about his motivation though. To me it seems that the World Cup was Del Piero's last masterpiece. Not that I mind though, my favorite player won the World Cup and had an absolutely stunning career. Perhaps he'll play a good season, but I think we'll be more depending on Bojinov, Marchionni, Nedved and Camoranesi.
