You still didn't answer : did you even see Maradona back then?
Because as I told you, I am old enough to have seen him.
Not only do the stats kill the Maradona argument, the eye test does too.
He joined a Napoli team that was hardly the trainwreck you described. He joined in june 84. They had finished 4th in the league in may 82 (so that's not 4 years like you said). Did he have an impact? Sure he had. But certainly not the one you make it out to be. It took several excellent additions before Napoli could fight for the title. The narrative that he took a piss poor team to two italian championships is just wrong. He was the best player on a pretty good team and had a good run for several years. That's HARDLY an incredible achievement given the roster (and coach) they had.
As for the Batigol/Trezegol comparison, they are definitely in the same league. I'd take Batigol, but Trezeguet achieved more in his career.
YOU decided the stats were screwed, I totally disagree with this. They may not fit your agenda, but Trezeguet was scoring a lot before Italy too. I compared the two players' numbers in the same league. Sure, they had different teams and situations. Somehow you feel Gabigol's later career shouldn't count. He was 34 when he left Italy. Trezeguet was 33. And he too had two unproductive seasons over 30. Yet you feel it's unair to count them for Gabigol but not Trezeguet? How so?
Number of "foreigner of the year" trophies in Italy? 1 for Gabigol, 1 for Trezegol.
Number of scoring trophies in Italy? 1 for Gabigol, 1 for Trezegol.
Number of player of the year awards in Italy? 0 for Gabigol, 1 for Trezegol.
Trezeguet has better european stats too.
They might not be comparable in your head, but since they pretty much have similar stats, similar styles and comparable trophies, I'd say they're VERY comparable.
