Paris St Germain capped off a brilliant week with a 3-1 Ligue 1 win over rivals Olympique de Marseille at Parc des Princes on Sunday and manager Luis Enrique did not shy away from the club’s ambition, saying the goal was to win everything this season.PSG took another big step towards the Ligue 1 crown after beating second-placed Marseille to extend their lead at the top to 19 points, having also knocked out six-times European champions Liverpool from the Champions League round of 16 on Tuesday.Chasing a first Champions League title, PSG have also booked a place in the semi-finals of the French Cup having won the Trophee des Champions in January. They will also be competing in the FIFA Club World Cup, which starts in June.“It’s been an exceptional week for us. A classic always motivates players from both teams, and I think we put on a great show tonight,” Enrique told reporters. “It’s difficult to get the ball to Marseille, and even more so to PSG. Each coach tried to play his cards right. It’s obvious that after a game like Liverpool, we had the chance to play a classic and that kept us on our toes.“I’m very happy with my team and the support of our supporters. Our aim is to win Ligue 1, to win all the trophies, that’s our hope. We’re aware of the huge challenge facing us, and we’re working hard every day to achieve (what we want).”PSG will next be in action at AS Saint-Etienne in Ligue 1 on March 29.On Sunday, Ousmane Dembele continued his prolific recent form by scoring the opener and Nuno Mendes made it 2-0 for PSG before half-time, with Pol Lirola’s own goal securing victory in the second half after Amine Gouiri had pulled one back. Luis Enrique’s side are still unbeaten after 26 games in Ligue 1 this season with eight matches to play.It means PSG could be crowned champions for the 11th time in 13 seasons during the next round of games on the last weekend in March. If Marseille lose at Reims and Monaco draw with Nice on Saturday, March 29, Paris would be able to wrap up the title with a win at Saint-Etienne the same day. Enrique said: “It was a good spectacle and a great game. We were maybe not quite as fluid as we have been but I am still very happy with the performance and it was an almost perfect night for us.”Dembele opened the scoring on 17 minutes, latching onto a Fabian Ruiz pass and going round Marseille goalkeeper Geronimo Rulli before changing direction and finishing emphatically into an exposed net. It was a 21st Ligue 1 goal this season for the division’s leading marksman, and a 30th in all competitions. Dembele has scored 25 goals in 20 appearances since mid-December.Ruiz also set up PSG’s second just before the interval as the Marseille defence switched off, allowing the Spaniard to make a run in behind before teeing up Mendes to score via a touch off Rulli. Marseille were staring at a third defeat in their last four games as well as a seventh successive league loss to PSG.Gouiri reduced the deficit soon after the restart as Adrien Rabiot latched onto a poor backpass by Mendes and went around home goalkeeper Gianluigi Donnarumma before setting up the striker. However, Dembele struck the post for PSG and the third goal arrived when substitute Lirola turned Achraf Hakimi’s low cross into his own net.Marseille are just two points ahead of both third-placed Monaco and Nice in fourth, while Lyon are a further two points back in fifth after beating Le Havre 4-2.In Montpellier, the clash between the bottom two was interrupted in the second half after flares were thrown by supporters, briefly causing a fire to break out in a stand at the Stade de la Mosson.Saint-Etienne were leading 2-0 when the action was halted in the 57th minute, with a decision taken to abandon the match altogether shortly after. Referee Francois Letexier confirmed during a press conference that the game had been abandoned on the order of the authorities after police were forced to intervene to restore calm.Local police reported seven minor injuries and two arrests. Lucas Stassin had scored twice for Saint-Etienne who were on course for a vital win in their fight against the drop despite being reduced to 10 men just before half-time. “This has been brewing for a while unfortunately,” admitted Montpellier coach Jean-Louis Gasset. “Maybe not quite to this extent, but it is almost logical that this was going to happen.”Montpellier are bottom of the table, five points adrift of Saint-Etienne, who are themselves a point behind Le Havre in the relegation play-off spot and three points away from outright safety. The trouble erupted just after Saint-Etienne’s second goal went in, while incidents also took place outside the stadium.The hotel where the Saint-Etienne team were staying had also been targeted overnight, with fireworks launched at its facade at around 3:00am local time, although police said there were no injuries or serious damage caused.
