Defender Raphael Guerreiro has completed his move from Lorient to Borussia Dortmund on a four-year deal.
On Wednesday, it was reported that Guerreiro had been allowed to undergo a medical with Dortmund's medical staff in Paris and it has now been confirmed that the Portuguese left-back has signed a long-term contract with the Bundesliga outfit for an undisclosed fee.
Sporting director Michael Zorc told the club's official website: "Raphael Guerreiro is a technically skilled player who feels in several positions at home. We are very happy that he chose Borussia Dortmund."
Guerreiro - who is currently representing his country at Euro 2016 - scored 10 goals in 102 appearances during his three-year spell at Lorient.
