AFP, PARIS: Angel Di Maria scored the only goal as Paris Saint-Germain claimed a controversial 1-0 Ligue 1 win at Nantes on Sunday that was marred by a bizarre late sending off.

Di Maria poked in a 12th-minute opener for the visitors, before producing a glaring miss later in the first half.

Emiliano Sala thought he had headed in an equaliser for Nantes, but was incorrectly denied by the linesman's flag.

There was late drama as Nantes centre-back Diego Carlos was sent off by Tony Chapron for appearing to accidentally trip up the referee, with the official responding by kicking out at the Brazilian and brandishing a second yellow card.

Unai Emery's visitors took full advantage of their good fortune, and draws for Monaco and Lyon earlier in the weekend, to move 11 points clear at the top of the table.

Claudio Ranieri's Nantes stay fifth, eight points adrift of fourth-placed Marseille.

World-record signing Neymar missed out for PSG with a rib problem but Edinson Cavani returned from injury, looking for the two goals he needed to break Zlatan Ibrahimovic's club goalscoring record.

Argentinian international Di Maria took advantage of Neymar's absence as he gave PSG the lead with his seventh goal of the season.

The front three were all involved as Cavani played a pass into Kylian Mbappe, and the teenager let the ball run for Di Maria to divert past Nantes goalkeeper Ciprian Tatarusanu.

Di Maria should have doubled the advantage before half-time, but after meeting Adrien Rabiot's pass six yards out with an open goal to aim at, he contrived to hit the crossbar.

Fifth-placed Nantes continued to plug away and came close to a leveller early in the second period, but Sala was denied by a sprawling Alphonse Areola after latching onto a slack Layvin Kurzawa backpass.

PSG almost took full advantage as Mbappe led a rapid breakaway, with Di Maria again the guilty party as he sliced horribly wide from the winger's cutback.

Ranieri's Canaries continued to trouble the runaway league leaders and Argentinian striker Sala glanced home a header from a free-kick, only to be flagged offside despite clearly being behind the last defender when the ball was played.

Romanian Tatarusanu made an excellent one-handed save to deny Mbappe, but Nantes couldn't create another clear-cut chance to equalise despite some late pressure.

The barely believable sending off in injury-time summed up a bitterly disappointing day for Nantes, with Chapron definitely the villain in the eyes of the home fans.

Monaco's goalless draw at Montpellier on Saturday handed Lyon the chance to leapfrog the principality club.

Karl Toko Ekambi gave the lowly visitors a shock 14-minute lead from the penalty spot, but the in-form Fekir dragged the hosts level shortly after half-time with his 14th league goal of the season.

The 24-year-old finished off a sweeping move he had started with a deft nutmeg on the right wing.

Bruno Genesio's men remain third, behind reigning champions Monaco on goal difference.

Saint-Etienne ended a 10-match winless streak with a 2-0 win over Toulouse thanks to goals from Robert Beric and Assane Diousse.
