Zlatan Ibrahimovic warmed up for next week's Champions League visit of Manchester City with a hat-trick as Paris St Germain trounced Nice 4-1 to move 25 points clear at the top of the Ligue 1.
PSG had already made certain of the French title, with eight games to play, and Saturday's latest victory at the Parc des Princes came at the expense of third-placed Nice.
Ibrahimovic, the league's top scorer, fired the hosts ahead from David Luiz's assist on 15, only for Hatem Ben Arfa to level matters three minutes later with a fine solo effort, as he curled the ball into the top corner.
The Swede grabbed his second with a 22-yard free-kick, 11 minutes before the break, while Luiz added a third home goal early in the second half with a near-post header.
Ibrahimovic completed the scoring in the 82nd minute, from Adrien Rabiot's pass, to take his tally of league goals for the season to 30.
The 34-year-old striker, who is out contract this summer, has now netted 38 goals in all competitions.
Next up for coach Laurent Blanc's team is Manchester City who travel to France for their first leg quarter-final tie on Wednesday.
