One week after being jeered by his own fans, Lionel Messi scored one goal and set up the other as Paris Saint-Germain won at a wasteful Nice 2-0 to reestablish their six-point lead at the top of Ligue 1 on Saturday.

Messi was booed by some PSG fans in last weekend's home defeat to Lyon, leading to increased speculation he could leave this summer.

With his goal and assist, Messi now has 1,000 goal contributions in his club career, according to ESPN Stats and Information, to reach yet another extraordinary milestone in his career.

Argentina's World Cup-winning star clipped in a cross from left back Nuno Mendes in the 26th minute. Then Messi's corner from the left was headed home by veteran defender Sergio Ramos in the 76th.

Nice were unbeaten in 14 matches overall before this game and went close to equalizing in the first half, but PSG goalkeeper Gianluigi Donnarumma kept out efforts from Nicolas Pépé and striker Terem Moffi.

Veteran defender Dante's shot came off the underside of the crossbar and appeared to cross the line in the 51st. But referee Jérémie Pignard was not alerted by goal-line technology that it crossed, even though video replays showed a goal should likely have been awarded.

Donnarumma kept out more shots from Pépé and Youssouf Ndayishimiye as Nice kept up the pressure on PSG, who have lost eight matches in 2023.

Nice hit the crossbar late on in a match of wasted chances.

Under-pressure PSG coach Christophe Galtier returned to the club he coached last season but Nice's ultras greeted Galtier with an insulting chant and unfurled a derogatory banner about him.

After the final whistle, Galtier walked over and sarcastically gave a thumbs up to the section of fans who insulted him, sparking an angry reaction. PSG sporting director Luis Campos intervened to encourage an upset-looking Galtier to leave the field quickly.

PSG moved back to six points ahead of second-placed Lens ahead of their match in Paris next weekend.
