No one having heard of them is not an argument.
I know it isn't, which is why I provide a basis to make his record somewhat comparable to other players to have graced Serie A. Effectively, someone scoring 30 in Nordahl's day is equivalent to someone scoring 18 in the 60s, 70s and 80s, which is still bloody good.
Top 10 goalscorers in Argentina, 7 of them are from the same era as Erico. That tells me that the era was leaking goal.
Undisputed, which is why I don't go around saying Erico was a 1.5 per game striker, but rather, I compare him to his contemporaries. Gio has one of them, he is playing, he is supposed to be the dog's bollocks and coming from one of River's most talked about frontlines, yet Moreno, Labruna and Pedernera jointly just about scored as many as Erico.
One reason those old records still stand and will continue to stand in Argentina is players no longer spend their entire careers there. That's why I also don't go around saying that him being the top goalscorer ever makes him better than Batistuta. Although arguably he was according to those who saw him. Different type of centreforward though so let's not even go there.
You can't say the same for Nordahl. He's the 2nd highest goal scorer ever with the highest goalscorer having played in the same era as Enrico an almost twice as many games as Nordahl. 3rd on the list is Totti, 4th is Meazza.
As I said, part of it is players in the 60s, 70s and 80s played a lot less games, against better defences. If I'm not mistaken, Hamrin, another stats animal from the 50s is 6th in the all-time list. He was a winger.
BTW, I think Totti is first by now, which obviously doesn't make him the best striker in Serie A history. In fact, he wasn't even drafted, nor was Vieri.
I can see the advantage of picking a Swede with similar characteristics to Vieri and an awesome scoring record. Just don't make him out to be Vieri on steroids, because he wasn't.
