The attacking midfielder sees similarities between himself and the Blaugrana attacker, and dreams of winning the Champions League
The Brazil international has put in a number of impressive displays since joining PSG from Sao Paulo in the January transfer window, and he is keen to follow in the footsteps of the 2012 Ballon d'Or winner.
"Messi shares my style of taking the ball and bringing it forward," Lucas was quoted as saying on the official Uefa website.
The 20-year-old then went on to stress that he has set his sights on winning the Champions League ahead of the quarter-final tie against Barca.
"It's the best competition in the world, a pleasure and a dream to play in. I want to win it.
"We have an opportunity now. We have a great team, a very capable team with great players, so we have everything to get further and we will prepare for it."
PSG host Barcelona on Tuesday in the first leg of their quarter-final tie, with a Camp Nou visit to follow eight days later.
