Fifa has dismissed a complaint by England of racial abuse during last year’s Under-17 World Cup final due to a “lack of sufficient evidence”.
Fifa said any sanction could be imposed only “on the basis of clear evidence”.
Last month Uefa found “no evidence to corroborate” claims Brewster suffered racial abuse in the Uefa Youth League.
Uefa initially charged Spartak Moscow defender Leonid Mironov over the incident during the game at Prenton Park in December.
Mironov admitted swearing at Brewster during Liverpool’s 2-0 victory but denied using racist language.
