Tottenham Hotspur winger made his debut against Juventus.
The Brazilian featured in the closing stages as Spurs closed out an impressive fightback to draw 2-2.
Tottenham are fortunate that PSG did not select Lucas in the Champions League group stages, making Lucas eligible for selection for Spurs following his transfer.
Lucas looked bright in his brief appearance, and sent a message to fans on social media after the game.
Lucas clinched his move to Tottenham on deadline day but he has not featured yet in the Premier League.
A lack of game time for Paris Saint-Germain has left Lucas short of match fitness and Spurs manager Mauricio Pochettino has been cautious in using him too early.
The winger could be in line for a start at the weekend for the first time when Tottenham are in FA Cup action - providing Pochettino is comfortable playing him on Rochdale's poorly maintained pitch.
