Paris Saint-Germain won the French Coupe de la Ligue by beating Lyon 2-1 in the final at the Stade de France to secure the first leg of a likely domestic double.
Edinson Cavani was the match-winner for Laurent Blanc's side, scoring a first-half brace, one of which came from the penalty spot, and while Alexandre Lacazette pulled a goal back in the second half, PSG proved too strong for a Lyon side who had beaten them in the French Ligue 1 just six days earlier.
The cup represents the second trophy won by the club from the French capital since their takeover by Qatar Sports Investments in 2011 and subsequent transformation into one of the wealthiest clubs in Europe, following their title triumph last season.
And their Coupe de la Ligue victory -- their fourth in the 20-year history of the competition -- could be followed by another Ligue 1 crown as early as next Wednesday, although they must hope nearest rivals Monaco lose on Sunday to secure the title.
PSG recently dropped out of the UEFA Champions League to Chelsea and their 1-0 loss in Lyon last weekend had heaped pressure on Blanc. Two consecutive games without scoring a goal since the loss of 40-goal leading scorer Zlatan Ibrahimovic to injury had also increased the pressure on misfiring record signing Cavani, but the Uruguayan produced a superb first-half display in which he scored twice and could have had two more goals.
The opener arrived with exactly three minutes played, Maxwell playing a one-two with Ezequiel Lavezzi and dinking the ball over advancing Lyon goalkeeper Anthony Lopes for Cavani to poke home from close range.
Lyon, back at the Stade de France for the first time since winning the Cup two years ago, might have equalised moments later, but Bafetimbi Gomis hit the side-netting after good work from his strike partner Lacazette.
Gomis then headed an Arnold Mvuemba corner straight at Nicolas Douchez, who was preferred in goal to regular PSG first-choice 'keeper Salvatore Sirigu, just as he had been in the earlier rounds of the competition.
However, Paris were on top and Cavani was unlucky not to score with a superb first-time volley from 25 yards that was saved by Lopes flying to his right.
Brazilian defender Alex then had the ball in the net following a Lavezzi free-kick only for the offside flag to cut short the PSG celebrations, but they increased their lead from the penalty spot just after the half-hour mark.
Lucas received a long ball forward from Thiago Silva in front of Lopes only to go down under contact from the Portuguese goalkeeper and the referee awarded a penalty. Lopes could do nothing to keep out Cavani's emphatically struck kick from 12 yards.
It was the former Napoli striker's 24th goal for the club since arriving in France last summer and he then squandered a good opportunity to complete his hat-trick when he blazed over after a piercing run by Lucas.
Lyon looked down and out at half-time but their coach Remi Garde made a tactical switch eight minutes after the restart, replacing right-back Mouhamadou Dabo with another forward in Jimmy Briand. Lacazette was moved across to the left and three minutes later he collected possession on the flank and cut inside before beating Douchez with a low shot from 20 yards into the bottom left-hand corner.
However, an effort from substitute Nabil Fekir that hit the side-netting was as close as OL came to equalising.
