@Abdull_tjay posted: "Emi Martínez concedes way too many bozo goals to be called the best, he’s not even top 5, asides penalty saves in Copa America which he’s good at he’s so bang average."
@tdnightingale wrote: "For what is certainly not the first time this season, Emi Martínez really should not be conceding there."
@jimmytozer said: "Another Emi Martinez howler. That guy is not top quality."

@AryanNaik134 called the World Cup-winning goalkeeper 'disgraceful' as he posted: "Ye Martinez I’m not defending u anymore pal that’s disgraceful keeping."
