Paris: Lucas scored twice in the second half as French champion Paris Saint-Germain eased past struggling Guingamp 2-0 on Saturday.
Lucas coolly slotted home a penalty and swept home his second goal 15 minutes later after a fine run and pass from left back Layvin Kurzawa, who was involved in a first-half collision with his goalkeeper Kevin Trapp.
Trapp went off at halftime clutching his right knee in a precautionary measure ahead of Tuesday's Champions League quarterfinal at Manchester City, with the tie poised at 2-2.
With that second leg in mind, coach Laurent Blanc rested Zlatan Ibrahimovic, winger Angel Di Maria, forward Edinson Cavani, midfielder Thiago Motta, center half Thiago Silva, and left back Maxwell.
Blanc handed rare starts to two 18-year-olds — midfielder Christopher NKunku and striker Jean-Kevin Augustin. Key midfielder Blaise Matuidi did play, but he is suspended for Tuesday's game.
Toward the end of the first half, Kurzawa needed treatment for a heavily bleeding nose after colliding with Trapp, whose knee slid into Kurzawa's face as they scrambled for a loose ball near the touchline.
Trapp was replaced by Italian Salvatore Sirigu for the second half.
PSG took the lead after NKunku was knocked over by defender Jeremy Sorbon and Lucas confidently sent goalkeeper Jonas Lossl the wrong way.
Guingamp striker Mevlut Erding had a poor game against his former team, missing an open goal.
The win moved PSG provisionally 28 points clear of second-place Lyon and third-place Monaco, which are separated on goal difference. Monaco plays away to Lille on Sunday, while Lyon won at Montpellier 2-0 on Friday.
The defeat leaves Guingamp six points above the relegation zone.
Elsewhere, striker Wissam Ben Yedder took his league tally to 14 goals as Toulouse keep alive its chances of avoiding relegation with a 4-0 home win against Corsican side Bastia.
With five matches remaining, Toulouse was four points behind Reims in 17th place.
Also, it was: Caen 1, Lorient 2; Saint-Etienne 1, Troyes 0; Angers 0, Ajaccio 0; and Reims 2, Nantes 1.
In Sunday's other games, Nice takes on Rennes, and struggling Marseille hosts Bordeaux having not won a home game in the league since Sept. 13.
