Since Greaves, i reckon.
This.
Shearer's as a goal scoring at Blackburn (and early Newcastle days) was absoltely sublime, his goalscoring record during that time was ridicilous and I doubt there is many people in the English game who have a better goals to games ratio, ever.
And although you can say Carroll is better in the air due to shear size and power, there's no way he's a better header of the ball than shearer ever was, both attacking it and flicking it on.
Can't argue with this. Good post.
