The 20-year-old agreed to join PSG in August, but requested to stay with his old club until the end of what proved to be a successful Copa Sudamericana campaign.

And having scored the opening goal in a 2-0, two-legged victory over Tigre in the final, Lucas Moura waved goodbye to his old team-mates and joined up with PSG at their winter training camp in Doha, Qatar.

"Choosing PSG is a challenge, a challenge for me," he told reporters.

"(Director of football) Leonardo helped me a lot with my decision, and so that I could stay with my old team in Brazil until the end of the season.

"I'm glad to know that Carlo Ancelotti counts on me. I'll try to do my best and give the best for the team. I always tried to be focused on Sao Paulo in the last few months. Now, I can think of PSG, who are a great club. I'm here to offer my assistance to my new team."

PSG have a proud tradition of fielding Brazilian stars, with Ronaldinho and Leonardo among those to represent the club, and the current squad can boast five with Lucas Moura's arrival.

He is looking forward to adding to that burgeoning legacy now that he has finally joined up with his new team-mates.

"PSG have a long history with Brazilian players and I hope that I can write a new chapter in this story and please the fans," he said.

"Everyone expects a lot from me, but I am very confident.

Lucas Moura will take part in his first training session with the club on Tuesday, but is not expected to feature in their friendly against Lekhwiya on Wednesday.
