Cape Town - Paris Saint-Germain have triggered the option to sign on-loan defender Serge Aurier on a permanent basis from Ligue 1 rivals Toulouse.
The Ivory Coast international linked up with the French champions on a season-long loan in July last year and has already helped his new team lift the Coupe de la Ligue trophy.
Aurier missed a month of action for Laurent Blanc's side earlier this year when he featured for the Elephants at the Africa Cup of Nations in Equatorial Guinea, where they went on to win the coveted title.
The 22-year-old right-back has now put pen to paper on a contract that will keep him at the Parc des Princes until June 2019.
He told the club's official website: "The project here at Paris Saint-Germain is exceptional. I am enjoying magnificent season, both on an individual and team level.
"I am very proud that the club is again showing its confidence in me. I will continue to progress to help the team reach the summits of the game, both in France and Europe."
PSG president Nasser Al-Khelaifi added: "Serge Aurier is a young player with enormous potential. Like his young team-mates, he represents the future of Paris Saint-Germain.
"It was logical that we trigger the option to buy. The club's project continues, especially our policy of conserving our best young players. Serge will become an essential element of the team in the future."
