Cristiano Ronaldo’s World Cup dream will face a potentially defining test as Portugal face highly-favoured Spain in the last-16.
Portugal got past an ever-difficult Croatia side in the round of 32 by the skin of their teeth, snatching a 94th-minute winner courtesy of Goncalo Ramos before Snicko came to their rescue to deny Josko Gvardiol an equaliser even deeper into stoppage time.
Ronaldo, 41, ended his six-tournament wait for knockout-stage goal in Toronto - albeit from the spot - and will now hope to inspire a famous victory over their Iberian neighbours Spain.
The European champions got off to a somewhat slow start after being frustrated by Cape Verde in their group opener but look like they’re well and truly in their groove now, with a statement win over Austria stoking expectation that they can indeed go all the way.
Here’s everything you need to know.
When is Portugal vs Spain?
Portugal’s last-16 clash with Spain kicks off at 8pm BST on Monday 6 July at the Dallas Stadium.
How can I watch it?
Viewers in the UK can watch the match on BBC One and stream it on BBC iPlayer, with coverage starting at 7:30pm BST.
Who will the winner face?
The winner will be pitted in a quarter-final tie with either co-hosts United States or Belgium, with that match set for 10 July in Los Angeles.
Team news
Roberto Martinez has no fresh injury concerns to contend with in his Portugal squad, with his only real conundrum coming over who should start on the right-hand side - will Pedro Neto keep his place ahead of Bernardo Silva or Fransisco Conceicao?
Spain remain without Nico Williams and Yeremy Pino after their respective injuries in the group-stage finale with Uruguay. Meanwhile, Spain have been managing the workloads of Lamine Yamal, Pedro Porro, Dani Olmo and Aymeric Laporte by limiting their training but this should not impact their availabilities.
Predicted line-ups
Portugal XI: Costa; Cancelo, Dias, Veiga, Mendes; Vitinha, Neves; Neto, Fernandes, Leao; Ronaldo.
Spain XI: Simon; Porro, Cubarsi, Laporte, Cucurella; Rodri, Pedri; Yamal, Olmo, Baena; Oyarzabal.
