PSG is now on a four-game winning streak, but Barca is also unbeaten in 11 and has won eight of those, and Lucas believes the hosts are the underdogs.
The home side took the game to their visitors from the start with Marco Verratti, Adrien Rabiot and Matuidi dictating the pace from the midfield for PSG.
The BT Sport enhanced video player is also available online. For PSG, it will be interesting to see how Julian Draxler fares in such a big game following his move from Wolfsburg last month as I think the Parisians will be up against it over the two legs.
And Marquinhos won't come cheap either, with the report going on to add that he could be sold for a world record fee for a defender, when PSG offload him.
Barcelona will have a mountain to climb when PSG visit Camp Nou for the second leg of their Champions League round of 16 fixture. Their second goal summed up the difference between the two sides in the first period.
Angel Di Maria has scored another sensational strike to put PSG up 3-0 over Barcelona in the 55th minute.
Barcelona warmed up for the trip to the French capital by thrashing Alaves 6-0 at the weekend. The only man Luis Enrique will be without is midfielder Aleix Vidal, who will miss the rest of the season due to nasty ankle injury picked up in La Liga.
And what you want more than most when you play a team like Barcelona, particularly in defence, is experience, but Emery will have to hope Kimpembe does the job for his team and keeps out the away goals, which could prove to be so crucial in this tie.
Barcelona have won nine of their last 11 games in the Champions League knockout stages (L2).
This was PSG's night, though, and Unai Emery's side will surely go on to secure a fifth successive appearance in the quarter-finals.
It was a night to remember for the Uruguayan: his 30th birthday, his first goal against Barcelona and a goal to top his best-ever Champions League tally in a season. However, he's never scored in 350 minutes of Champions League action against Barcelona. Thomas Meunier surged forward from right-back and set up Cavani, who thumped home his 34th goal of the season in all competitions. Since the end of the group phase, Barca have won six and drawn two of their Primera Division games (they lead Real Madrid by a point) and have reached the Copa del Rey final.
