But before a ball had been kicked, coach Fernando Santos prophesied an unlikely victory.
“From the first moment, the first qualification game, he said, ‘We will win Euro 2016,'” Portuguese right-back Cédric Soares tells CNN Sport.
“He put it up on the board. In that time, no one really believed him. And during the qualification games he was already putting the same message on the board — ‘We will win Euro 2016.’ We hadn’t even qualified!”
Friday marks four years since Portugal’s 1-0 victory over France in the final of the Euros.

“It was absolute madness, there were incredible scenes when we got out of the airplane,” says Fonte, who starred throughout the knockout rounds in 2016.
“Even in the air, we had two fighter jets coming alongside us when we got into Portuguese airspace. I remember seeing them with the Portugal scarf and flag in the airplane, that was incredible.
“Then we landed … I started seeing people waiting for us outside the airport. And then the bus parade, there were millions and millions of people in the streets celebrating with us. No one will ever forget that moment — it was just an unbelievable thing to just be part of, unbelievable.”
