The 20-year-old attacking midfielder is regarded as one of the brightest prospects in world football and moved to les Rouge-et-Bleu this month after the club agreed a reported 35-million-euro fee with Sao Paulo in August.

Sir Alex Ferguson's team were among several sides looking to sign Lucas, but the Brazilian said Leonardo's influence had persuaded him to ignore other offers.

"Manchester United wanted me but I talked a lot with Leonardo and he convinced me," Moura told Telefoot TF1.

"It's an honour for me to play with (Zlatan) Ibrahimovic," he added, speaking about the lure of PSG.

"I will learn a lot from this side."

Lucas has scored twice in nine Copa Sudamericana games this season and his father has stressed that his son's talent is matched by his level-headed approach.

"Lucas is a modest kid," said Jorge Moura.

"He never lost his head and this is priceless."

PSG sit top of Ligue 1 in the winter break with 38 points, leading Lyon on goal difference.
