Does your definition of being a legend means being old, slow and almost useless?? If so then your definition is spot on, no other team has a great legend as Del Piero.
And don't get me started on Totti, wasted career on a mid to top 4 table club, never performed for the NT and won a grand total of 1 Scudetto. Awesome.
Seriously though, you have tunnel vision. Spread your horizons a little bit, if Del Piero and Totti are the only guys you consider to be legends, it just means you don't watch enough football. Del Piero is a local guy, revered by Juve fans but only by Juve fans, he's never been the best player in the world, not even in the top 10. Totti is a much better player than Del Piero as well, he was just in a lower class team his whole career and never proven in a real top team. A shame really.
BTW, Messi in his club career has already won as much as Del Piero has and received more international accolades such as World Player of the Year and European Footballer of the Year. What about Eto'o? Won everything with Barca and Inter, he won the fucking treble not once, twice! And he still has a career, Del Piero would kill to have that.
Yet they are not legends? LOL.
