PARIS (AFP) - Ivory Coast international defender Serge Aurier has joined Paris Saint-Germain on a season-long loan from fellow French top-flight side Toulouse, the Ligue 1 champions announced on Wednesday.

The deal, which includes an option for PSG to make the move permanent, will see Aurier, 21, compete for the right-back spot at the Parc des Princes along with Dutch international Gregory van der Wiel.

"We are particularly delighted to welcome this young player to our club," said PSG president Nasser Al-Khelaifi, who called Aurier "one of the most promising young players in world football".

Aurier was voted the best right-back in France last season and shone for Ivory Coast at the World Cup in Brazil despite his country's elimination in the group stage.

"To play at PSG with these fantastic players is a childhood dream," said Aurier. "I will give everything to help the team reach the top." Aurier, who will wear the No. 19, becomes the capital club's second recruit of the transfer window following the arrival of Brazil defender David Luiz from Chelsea.

Earlier on Wednesday PSG allowed defender Christophe Jallet to join Lyon in a deal worth up to €1 million (S$1.6 million).
