Southampton have signed FC Twente defender Cuco Martina.

Talking after the deal was confirmed, Martina said there were many factors that made a move to Southampton, who will play in this season's Europa League, attractive.

"I'm very happy to be here at a big club like Southampton," he said.

"I've followed Southampton now for two years and I see they are now a big club. I know Ronald Koeman and Erwin Koeman - I worked with Erwin for one year and everything was good. He knows my qualities and I know what he wants.

"It was a dream for me to play in the Premier League and finally I can play now. I hope to play many games and show the fans who I am."
