The 20-year-old represented Spain at the Paris 2024 Olympics, netting once in his four appearances at the tournament.

Since joining Porto in August 2024, he has netted 11 goals in 11 matches in all competitions, netting seven of those in the Primeira Liga in seven appearances, averaging a goal every 68 minutes.

Barcelona's Marc Casado has also been added to Luis de la Fuente's squad after impressing with his appearances in the LaLiga leader's midfield amid its injury struggles.

Casado has attempted the most passes (850) and completed more (729) than any other Barcelona midfielder in all competitions this term (90.6 per cent success rate).

"At the age of 20, [Omorodion] has football potential. He burst onto the scene in a way that has attracted attention. It's time to give him continuity," De la Fuente said.

On Casado, he added: "It's all thanks to his confidence, commitment and ability. There are very good players who need that kind of demand to shine. He is ready, but he still has room for improvement."

Spain captain Alvaro Morata is also part of the squad despite being rushed to hospital after suffering a head injury during AC Milan training, but De la Fuente insisted the 32-year-old was fine.

However, Pau Cubarsi has been left out after sustaining a facial injury during Barcelona's UEFA Champions League win.

UEFA Nations League holder Spain has already qualified for the quarter-finals but is yet to clinch top spot. It faces Denmark on 16 November (AEDT) before finishing the group stage against Switzerland three days later.
