Two European footballing powerhouses meet in the last 16, where Portugal and Spain go head-to-head.
Portugal are an unpredictable entity. The 2-1 win over Croatia in the previous round raised questions over the team's defence, and while Cristiano Ronaldo did score the opener, there is still a consensus that Portugal play their best football when he is not on the pitch.
Roberto Martinez's side will now take on a Spain side who are quietly going about their business, which is often the case in major tournaments, and suddenly they are lifting the trophy come the end of it.
But Portugal knows what it takes to beat Spain, overcoming their neighbours on penalties in the final of last year's UEFA Nations League.
It's set to be a thrilling clash that could be a passing-of-the-torch moment between two generational superstars, Ronaldo and Spain's Lamine Yamal.
