French Ligue 1 club SC Bastia declared on Sunday that they would not accept any punishment from authorities for the brawl and pitch invasion that marred the end of their match with Nice on Saturday.

At the end of the game at Nice's Allianz Riviera stadium, which Bastia won 1-0, the visitors' substitute goalkeeper Jean-Louis Leca took to the pitch brandishing a Corsican flag, portraying a Moor's head, the emblem of the island, above his head.

Players from both sides then clashed and dozens of supporters forced their way onto the pitch in an apparent attempt to get at Leca.

However, a statement issued by Bastia read: "We will not accept any punishments to Sporting Club Bastia or any suggestion that Jean-Louis Leca played the role of provocateur."

They added that Leca simply "wanted to display with conviction and in a peaceful manner his pride in what he is — a Corsican player who had won a hugely important derby for the first time in 20 years."

Four men were later arrested and remanded in custody after invading the pitch, and both clubs are likely to be punished by the French league.

The incidents came after a government decree ordered that no travelling supporters could attend the game between the two rivals.

Elsewhere in Ligue 1 Marseille continue their impressive start to the season by winning their eighth game on the run – to equal a club record.

Marseille beat Toulouse 2-0 at the Stade Velodrome to move seven points clear at the top of Ligue 1.

First-half goals from Nicolas Nkoulou and the in-form Andre-Pierre Gignac proved enough for Marcelo Bielsa's side to take all three points as OM matched their previous record for consecutive league victories set in 1937 and in 1998.

OM, who have won every game since starting the campaign with a draw and a defeat, are seven points above reigning champions Paris Saint-Germain

Marseille were looking to pick up where they left off before the international break and Bielsa's starting line-up was unchanged from that which triumphed 2-1 at Caen a fortnight ago.

There was a new record crowd at the recently renovated Stade Velodrome, with the figure of 61,846 beating the previous mark of 59,120 set in the rugby World Cup quarter-final between Australia and England in 2007.

The home fans almost saw their side fall behind early on against an in-form Toulouse as Steve Mandanda turned a Martin Braithwaite shot onto the bar.

But OM got the breakthrough in the 21st minute, Cameroon defender Nkoulou rising to convert a Dimitri Payet free-kick, the ball appearing to go into the net off his shoulder.

Florian Thauvin then shot just wide before the home side doubled their lead nine minutes before the interval as Gignac – who starred in France's friendly win against Armenia in midweek – netted his 10th goal in as many league games this season.

Toulouse initially lost possession from a throw-in and then failed to clear a cross from the Marseille left, allowing Gignac to sweep the ball into the net against his old club.

The last time the south-coast club won eight league games in a row was in 1998, when their run was ended in a 2-1 defeat at Lyon, who will be Marseille's opponents next weekend.

Bordeaux missed the chance to go back above PSG into second as they failed to hold onto the lead given to them against Caen through a first-half penalty by giant Malian striker Cheick Diabate.

Caen equalised 13 minutes from the end when substitute Herve Bazile shaped to cross from the left and wrong-footed goalkeeper Cedric Carrasso, who had come off his line, before rolling the ball into the gaping goal.

Yoann Gourcuff scored a brace as Lyon extended their unbeaten run to six games with a 5-1 thrashing of 2012 champions Montpellier.

On Friday, PSG came from behind to beat Lens 3-1 in a remarkable encounter played at the Stade de France which featured three red cards in the space of six second-half minutes.

On Saturday, Monaco warmed up for their Champions League clash with Benfica by beating Evian 2-0 at the Stade Louis II thanks to a Joao Moutinho penalty and a second-half Yannick Ferreira Carrasco strike.

Saint-Etienne went fourth with a 1-0 win at Lorient, but Lille, who entertain Everton in the Europa League on Thursday, went down 2-1 at home to struggling Guingamp.
