Oliver Torres is not thinking about his prospects at Atletico Madrid once his loan spell with FC Porto ends next year.
His sole focus, he says, is on having a strong season at the Dragao stadium in Portugal.
Torres is on international duty with Spain's under-21 squad, who take on Austria in Friday's European U21 Championship qualifying match in St. Polten.
The Spanish midfielder told Onda Cero radio: "I'm not thinking about a return [to Atletico] right now. I don't know what will happen.
"Right now, I'm very happy at FC Porto. I'm only thinking about learning, growing as a player and enjoying this experience.
"Whatever has to happen will happen."
FC Porto have an option to buy Torres for €20 million once his loan deal expires in December 2017.
Torres, who is under contract with Atletico until June 2018, started in just 14 games in all competitions for Atletico in the 2015-16 campaign and left the Rojiblancos this summer in search of more playing time.
"It's not easy to succeed in La Liga when you are young," Torres said. "Each player has his progression, his time.
"I have to continue to grow and gain experience."
He returned to Porto for a second spell on loan having enjoyed a strong 2014-15 with the Portuguese giants, starting 28 games for them to help the Dragoes finish runners-up behind Benfica in the Primeira Liga.
