That's a big assumption. I bet without coke he wouldn't have dared to do his hand of god act.
One needs more than coke to do what he did in 1986. One needs to be extraordinarily gifted, only for the likes of Pele, Ronaldo, Ronaldinho, Garrincha, Messi, Zico, Cruyff, and Maradona could ever do.
I hated his guts as a kid because of 1990 (another hand of god, and the feeling he took from Baggio and Schillaci’s Italy a final that was our god-given right), but I’ve come to realize later that he was one of the last great footballers to be (flawed) men first and athletes second. The way he spoke of guilt and regret, his embarrassingly public mistakes... they made him more real than a robotic superman like Cristiano Ronaldo will ever be. And some of his highlight reels are ridiculous.
