Hmmm there could be a couple of characters you could be talking about. But, from what comes to mind when I think of a character from Blue Lock who “looks like a zombie” I think of Rin during all of the panels where he was in his flow state and had his tongue hanging out his mouth like a madman

Though, Don Lorenzo is also described to be a ‘zombie’ of sorts due to his appearance in general so that could be who you’re referring to, as well. I’m not sure what meme you had in mind but if I ever saw it then I could definitely name who it is!
