Lucas Moura had other offers in the January transfer window but joined Tottenham to have fun again, according to his former Paris St Germain team-mate Serge Aurier.
Aurier, who also swapped the Ligue 1 champions for Spurs last summer, played a major role in persuading Lucas to follow suit.
The pair are close friends after their time together in France.
A Tottenham video posted on Twitter to announce Lucas' arrival ended with him and Aurier sharing a carefully choreographed handshake.
