Yoann Gourcuff has signed a four-year contract with Bordeaux after the French club triggered the 15-million euro buy-out clause in his 12-month loan deal from AC Milan.
The 22-year-old French international playmaker has made a huge impression at the Ligue 1 outfit since arriving on loan from the Rossoneri last summer – providing much of the impetus that has driven Laurent Blanc's men to the brink of the French league title.
A point at struggling Caen this weekend will ensure they pip Marseille to the championship, and they will approach the game in high spirits after securing the services of the man named Ligue 1 Player of the Year last week.
"AC Milan announces that FC Girondins de Bordeaux have exercised the option to acquire Yoann Gourcuff, whom we wish the best for the remainder of his career," read a short statement from AC Milan.
"I'm very happy to be continuing this adventure with Bordeaux," Gourcuff told Bordeaux's official website. "This decision was made over the course of the season.
"Together, we've created a great team by creating great human bonds within the squad.
"I learnt a lot during my time at AC Milan and I'd also like to thank the players and staff of that club where I really did my apprenticeship at the highest level," he continued.
"The confidence shown in me by coach Laurent Blanc and my teammates since the start of this season and the club's ambitions for the coming season, as well as the unfaltering support of the fans all convinced me to accept this new challenge."
Bordeaux have already claimed the French Super Cup and French League Cup this season and can wrap up their first league title in ten years on Saturday night.
