Real Sociedad striker Portu says their former Premier League stars are up for tonight's Europa League clash against Manchester United.

Adnan Januzaj will be facing his former club, while former Manchester City captain David Silva is also set to start.

"All you can do is learn from him," Portu told theMirror of Silva.

"He's a spectacular footballer and person. Technically he is one of the best players I have seen and he's a genius both with the ball at his feet and tactically. In the dressing room when he talks, you listen.

"He is used to playing against United and at Old Trafford in the derby and he is determined to go back there and win."

Another familiar face likely to be lining up on Thursday is Januzaj.

"Adnan is very excited about the game and was really happy with the draw when it was made," Portu continues. "Every player likes facing their old teams.

"He told us everything about how special Manchester United is and still has a lot of affection towards the club.

"We all know what a huge club it is all around the world and it is a great challenge for us to try to beat them."
