Mali midfielder Mohamed Sissoko and Italian goalkeeper Salvatore Sirigu have completed moves to Paris Saint-Germain, the French club announced on Thursday.
Sissoko, 26, was born in France but represents Mali at international level and has never previously played in Ligue 1. He enjoyed spells at Valencia and Liverpool before moving to Juventus in 2008 and has now penned a three-year deal at the Parc des Princes.
"For me, it's a huge pleasure to play at PSG," said Sissoko at a press conference. "I chose this club because it's a club with a very ambitious project and the people here have told me some very important things."
Meanwhile, 24 year-old Sirigu, who has two caps for Italy, has signed a four-year contract after leaving Palermo. "Why did I choose Paris? It's a club that wants to create something," said Sirigu, Italy's third-choice goalkeeper.
"I'm very happy to be here and to be a part of such a team. I'm honoured by the interest shown in me. The team is going in a direction that suits me."
The moves are a further indication that PSG are determined to establish themselves as a major force following the arrival of Qatar Sports Investments (QSI) as majority shareholders and the appointment of Leonardo as sporting director.
The club have now made seven signings this summer, with Nicolas Douchez (Rennes), Kevin Gameiro (Lorient), Milan Bisevac (Valenciennes), Blaise Matuidi (Saint-Etienne) and Jeremy Menez (Roma) already having put pen to paper.
More are likely to follow, with Leonardo reportedly close to agreeing a sensational €30 million ($43 million) swoop for another Palermo player, Argentinian playmaker Javier Pastore.
