Zlatan Ibrahimovic scored twice as Paris Saint-Germain beat Lyon 5-1 to open up a 17-point lead at the top of the French league Sunday, glossing over yet another blunder from goalkeeper Kevin Trapp. Ibrahimovic, the club's all-time leading scorer, put PSG ahead in the 11th minute with a neat finish and right-back Sergie Aurier made it 2-0 when he headed in Angel di Maria's cross just six minutes later. Striker Edinson Cavani almost made it 3-0 just moments later when he poked wide, but Lyon was handed an unexpected lifeline in the 24th. Trapp was caught straying way off his line when midfielder Jordan Ferri tried a speculative shot from 25 meters and, as he backpedalled, haplessly pushed the ball into this own net. Trapp did the same two weeks ago, when PSG beat Troyes 4-1. Sunday's gaffe was the German goalie's fifth significant mistake he has made this season in a side that has faced hardly any pressure so far — raising doubts as to whether he is equipped to play at the top level PSG strives for in Europe. Shortly after his mistake, PSG's fans ironically cheered Trapp when he caught a routine high ball. Thankfully, all is well in attack, with Cavani turning in Di Maria's cross from the left flank in the 61st minute. Ibrahimovic then punished a foul by defender Henri Bedimo to make it 4-1 from the penalty spot in the 77th, his 12th goal in 10 games. Di Maria rounded off with his third assist of the night, supplying the pass for substitute Lucas to run through and fire a powerful shot into the left corner in injury time. In a further boost for coach Laurent Blanc, midfielder Marco Verratti returned from injury and replaced Adrien Rabiot for the last 20 minutes. Although Lyon secured a morale-boosting 2-0 win away to Valencia in the Champions League in midweek, coach Hubert Fournier's side has lost four and drawn one of its past five league games, and is 22 points behind PSG in sixth spot. Angers and Monaco are 17 points behind PSG but newly-promoted Angers — which equalized late on in a 1-1 home draw with Bordeaux — leads Monaco on goal difference. Earlier, emerging Brazil right back Fabinho's late penalty earned Monaco a 1-0 win against Saint-Etienne. Marseille had midfielder Abdelaziz Barrada sent off early in the second half as it rallied to a 1-1 home draw against Corsican side Gazelec Ajaccio. Dortmund cuts Bayern's lead Pierre-Emerick Aubameyang scored one goal, set up another, missed a penalty and had two goals ruled out in Borussia Dortmund's 4-1 win at home over Eintracht Frankfurt in the Bundesliga Sunday. Dortmund cut Bayern Munich's lead to five points, while only goal difference was keeping Frankfurt out of the relegation zone. Earlier, an injury time strike by defender Caiuby earned Augsburg its first ever win over Schalke in a 2-1 victory. Juve stuns Viola Mario Mandzukic and Paulo Dybala struck late as champion Juventus continued its Serie A fightback with a stunning 3-1 win over Fiorentina in Turin Sunday. Juventus, claiming its sixth consecutive league win following a disastrous start to the season, moved up to fourth place at the expense of Roma to sit six points behind leader Inter Milan. Inter had stretched its lead over Fiorentina to four points with a 4-0 away win at Udinese Saturday and although La Viola remains in second place Paulo Sousa's title challenger is now four points off the pace. Napoli remains third, also four points off the pace, after being held to a scoreless draw by Roma, which dropped to fifth to sit seven points adrift. — Agencies
