He admitted it was a fluke himself!
On that basis perhaps it shouldn't be talked about as the greatest goal, seeing as he didn't mean to flick it that way.
Off topic, but his goal in the world cup vs Argentina was better imo:
This and Zidane's volley are the two best goals of all time for me if we're taking the stage in to consideration. His control is ridiculous. Much prefer the likes of this to long range blasters - most of them that go in the top corner could have ended up anywhere.
As for the Premier League I'd say yeah, Bergkamp vs Newcastle. Where's he said it was a fluke?
