Also, Baggio's performances in Italia 90 and USA 94 make him a great. It's unfortunate that his knees let him down more often than not, but had the man been able to play without the accompanying pain, he'd have been in the discussion for GOAT. He was that good; he was such a sublime footballer and possibly the greatest talent Italy ever produced.
Nope. He didn't have the legs or the consistency. Same for Ronaldinho. You can't be a GOAT if you play great for 3 seasons and then disappear into oblivion.
Why? Because the truth might be painful for butthurt and biased Juventus fans. Ask any partial and objective fan who is the greater/better footballer overall, and 70%, if not more, would probably choose Zizou.
Del Piero for Juve is better than Zidane; Zidane overall is the better/more impactful footballer. Now, had Del Piero not suffered that injury in 99, we might be having a different discussion.
