Figueroa's is easily worthy of the list. Bentley's isn't mind.
Bentley's isn't either, but Figueroa's is not that rare. You see a couple of goals from quick free kicks from own half a season across Europe. Also, I think it is easier to score such a goal in a dead ball situation. It was a good effort, but not deserving of anything like the tag goal of the decade.
Another more deserving contribution that is missing is Essien's v Arsenal.
