Paris St Germain have continued their summer spending with the arrivals of Salvatore Sirigu and Mohamed Sissoko at the Parc des Princes.
Mali international midfielder Sissoko makes the switch from Juventus, agreeing a three-year deal with the French club to return to the country of his birth.
"It's a great pleasure to play for PSG," he told the club's official website. "I chose PSG because the club has a very ambitious project. The club made me want to come. I did not hesitate.
"I've never played in France. I now have the opportunity to experience this championship and impose myself. I hope to bring more to the team."
Goalkeeper Sirigu, 24, has penned a four-year deal following a move from Palermo.
"I am very pleased to sign for PSG," he said. "I am honoured. I will learn French as quickly as possible in order to communicate with my team-mates."
PSG have now brought in six new players for the start of the Ligue 1 season, as well as former Inter Milan coach Leonardo as their sporting director, and the Brazilian has not ruled out further signings before the transfer window closes next month.
"Mohamed has played for Valencia, Liverpool and Juventus, and has extensive experience despite being only 26," Leonardo said. "He will bring much to the club and the team.
"Salvatore is a great player. Playing abroad will be a great experience for him on a personal level and for his game. Recruitment is ongoing."
It remains to be seen whether PSG will win the race for Palermo star Javier Pastore, who is also said to be heading for talks with Chelsea.
