Dude the amount of times i've ask persons that very same question
the answer is of course, no.
his CL final goal was majestic, and his chipped penalty in the '06 final was ballsy, but all of that was done when his reputation as one of the greatest was already cemented because of two goals against a very disjointed brazil side. I mean first thing's first, if he doesn't score vs. brazil he doesn't win the ballon d'or and thus probably doesn't get a move to real madrid to score that '02 goal.
it's funny how the football works.
but yeah, zidane had a knack of scoring when everyone was watching, which is why he's regarded as one of the best of all time (mostly by madridistas or people who didn't watch him week-in-week-out). conversely, henry usually failed to score when everyone was watching which is why his reputation is about 1/5th that of zizou's even though henry was utter magic, and CONSISTENT magic, for damn near a decade. ronaldinho didn't score in paris and had a poor world cup (not his fault) so he never REALLY got the praise his beautiful play deserved except from la liga watchers.
