Paris St Germain have confirmed the signing of Maxwell from Barcelona for an undisclosed fee, rumoured to be in the region of €3.5 million.
Maxwell, 30, has been on the fringes at Barcelona this campaign, making just twelve appearances for the Catalan giants.
"From my first conversation with (director of football) Leonardo, I felt really wanted,'' Maxwell said. "The invitation to join Paris made me very happy. This suits from the path that I have taken before (playing for Ajax, Inter Milan, and Barcelona). The project and the prospects motivated me.''
Leonardo added: "I have always admired Maxwell. I have followed him throughout his career. I'm really happy to have signed him.''
Maxwell, who becomes PSG's first signing of the January transfer window, has agreed a three-and-a-half year deal with the club.
Since his 2009 move from Inter Milan, the full-back may not have established himself in the first-team at the Camp Nou, but has picked up two La Liga titles, two European Supercups, two Club World Cups and a Champions League trophy in his time in Spain.
The player underwent a medical in Paris on Thursday morning, with the French league leaders announcing the capture on their official website in the afternoon.
Formerly of Cruzeiro, Ajax and Inter Milan, Maxwell will offer the French side versatility and experience in the full-back positions.
The signing of cover at left full-back was a priority for PSG this January, as they look to cover for the absence of Siaka Tiene, who is representing Ivory Coast at the African Cup of Nations tournament over the next month.
