I think he's referring to 94'.
I believe so too. But what exactly about it?
I remember that world cup like it was played yesterday. Italy had a really good team, which as Italy usually does, started slow and didn't play attacking football. It was still a team that had Maldini, Baresi, Donadoni, Costacurta, Tassotti, Albertini and Massaro, who came to the WC as CL winners, destroying Barcelona 4:0 in the final. And that's in addition to some other star players.
Baggio, in 3 knock out matches, was indeed the star of the team and played excellent, but it's not like he was single handedly carrying Slovakia or Honduras to a WC final. He was simply the best player of an excellent Italian squad.
Sneijder did the same thing for Holland at WC 2010.
Baggio was a fantastic player and talent. I used to put him slightly above Del Piero. Now, when I can compare their careers, when I can think of their best moments, the periods when they had the form of their lives and everything else, I can claim that Del Piero was the better player. Slightly better, but better.
I think that Del Piero's form in the recent years is clouding the judgement of many. For Baggio we remember only his best period while for Del Piero we're under the influence of yesterday's happenings and performances.
If they were both in their prime and played together in Juventus today, I think that DP would have been the star of the team.
