Messi's goal-to-game ratio is 0.76.
the only people with a similar goals-to-game ratio are Eusebio (0.73), Jean-Pierre Papin (0.74) and Marco Van Basten (0.75).
the only people with a better goals-to-game ratio are Alfredo Di Stefano (0.84), Ferenc Puskas (0.87) and Gerd Müller (1.00).
worth pointing out, though, that Müller, Papin and Van Basten have played much less games & goals than Messi. he's right up there with el Saeta Rubia, the Black Panther and the Galloping Major, which is fucking mental.
