211, following to Juve.com guys. They say this is his 14th, so they also counted that ''own goal''. Hurra Juventus magazine also credits that goal to Del Piero. So 211! :D
That statistic in Tutto Sport is a bit weird... For example, Nordahl has 221 goals for Milan, and Giuseppe Maezza has 246 for Inter.
EDIT - I see someone already pointed it out, hehe.
