Hojlund linked up with fellow substitute Andreas Skov Olsen to give Denmark the advantage, making up for Christian Eriksen's first-half penalty miss.

Denmark started brightly, and Mika Biereth forced an early mistake as he charged down Diogo Costa's attempted long ball. The goalkeeper recovered well, though, scrambling back to turn the ball wide for a corner.

Kasper Schmeichel denied Pedro Neto with a fine save moments later, but the clearest opening came in the 23rd minute as Renato Veiga was penalised for a handball in the box.

Eriksen stepped up to the spot, but his was a poor strike, with Costa comfortably getting across to his right to keep it out.

Biereth forced another great save out of Costa 10 minutes before the break, meeting a bouncing cross on the half-turn but seeing the goalkeeper react to tip it wide.

Denmark kept the pressure on in the second half, with Gustav Isaksen's drive tipped just wide by a sprawling Costa before Hojlund fizzed a low shot just past the far post.

Hojlund hit the mark moments later, though. Denmark cut Portugal open with one-touch passes, and the Manchester United forward was unmarked in the middle to guide Skov Olsen's cross into the bottom-right corner.
