FIFA Secretary General Fatma Samoura has congratulated Portugal on reaching the knockout stage of the Word Cup - and praised their opponents, Iran.
The reigning European champions were held to a 1-1 draw by Iran in their last group-stage match overnight, which made Portugal runner-ups in Group B.
They will face Group A leaders Uruguay in the round of 16 game at Sochi's Fisht Stadium on Saturday.
"Portugal, congratulations. Iran you fought very hard last night and can hold your heads high," Samoura wrote on her Twitter account.
