The Portuguese Football Federation (FPF) has entered into a partnership with fashion label Sacoor Brothers.
The deal will run through to 2020, with Sacoor Brothers serving as the official fashion partner of Portugal's national team.
The agreement will cover all players, team coaches, entourage, technical staff, management and administration involved with the team.
FPF president Fernando Gomes said: “Sacoor Brothers, like FPF, is a brand that is both Portuguese and international. We will build a relationship of trust, competence and mutual respect between the two major national institutions.”
Portugal is playing Morocco this (Wednesday) afternoon in its second group game at the 2018 Fifa World Cup, having drawn 3-3 with Spain in its opening match last week.
