Youssouf Sabaly has joined Bordeaux on loan until the end of the season but signed a new contract with parent club Paris Saint-Germain before departing the capital for southwestern France.
Sabaly, 23, is a PSG youth academy graduate and spent last season on loan with Nantes, scoring two goals and assisting another in 28 appearances.
The full-back joins Bordeaux on loan until the end of the campaign but added two more years to his contract with Les Parisiens, keeping him at the club until 2020, before formalising his arrival at Matmut Atlantique.
Speaking to PSG's official website, the former France youth international expressed his delight at the club's decision to offer him and extended deal.
"I am honoured by this declaration of confidence by my formative club," Sabaly said. "I will now embark upon a new adventure, one which will enable me to continue to progress."
Bordeaux finished 11th in Ligue 1 last season and parted ways with former coach Willy Sagnol back in March.
The six-time French champions have since appointed Jocelyn Gourvennec as their new boss and Sabaly told Bordeaux's official website that a conversation with the 44-year-old helped to convince him of the move.
"I am very familiar with the club because I have been to Bordeaux many times," he said. "When I was younger, I enjoyed watching the team play and I liked them very much.
"As soon as I heard that the Girondins were interested, it was really important for me to come to see the facilities and to listen to what the coach had to say. His speech was conclusive. Because of that, I have signed for the Girondins."
Sabaly, who also spent two seasons on loan with Evian in Ligue 1 between 2013-15, will be reunited with Jeremy Menez and Thomas Toure in Bordeaux -- two players he knows well from his time with PSG and in the French youth ranks before the later opted for the Ivory Coast at senior level.
"For the most part, I am going to have to get to know everyone," he said. "However, I do know Thomas Toure already from our time together at youth level for France and I also know Jeremy Menez a bit from PSG."
Sabaly replaces France international Mathieu Debuchy as Bordeaux's right-back after the Arsenal man endured a disappointing loan spell in Ligue 1 for the second half of last season.
Internationally, the former helped France to reach the semifinals of the 2010 UEFA European Under-17 Championship in Liechtenstein and he was also part of the squad that won the 2013 FIFA U20 World Cup in Turkey.
"Individually," Sabaly said about his Bordeaux loan, "my objective is to continue to progress and to move on to the next level."
