Champions League: PSG boss Enrique calls for cool heads in Chelsea clash
The Ligue deFootball Professionnel,which organises the top two divisions in France, sanctioned PSG's request to reschedule their home match with Nantes which fell in between the first and second legs of their last-16 tie against Chelsea on 11 and 17 March.
Though Nantes' executives agreed to the arrangement,the Collectif Supporters Nantais (which brings together the main Nantessupporter groups) was furious.
"We learned with astonishment of the postponement of the match between Paris Saint-Germain and FC Nantes to a later date, decided for the sole purpose of favouring PSG in its double confrontation in the Champions League," the Nantes collective said.
"This is not an isolated case. Last season, PSG's visit to Nantes was moved for the same reasons. The exception is becoming the norm French clubs must serve PSG's interests.

"If the French football authorities have chosen, for a long time, to serve PSG's interests, the leaders of FC Nantes have, for their part, the duty to defend ours. Accepting this postponement amounts to sacrificing the club for the exclusive benefit of another."
PSG will play Nantes on 22 April at the Parc des Princes, the LFP confirmed on Tuesday, three days after PSG host Lyon at the same venue.

Neither of the sides will be in action during the break for international games.
PSG resume their hunt for the title on 3 April with a home game against Toulouse. Lens face northern rivals Lille on 4 April.
Should PSG eliminateLiverpool,a semi-final against Bayern Munich or Real Madrid would fall on 28 or 29 April then 5 or 6 May. A Ligue 1 game against Lorient sits between those dates and, with no window left, would have to be played.
Lens added in its statement: "Beyond this specific case, the question raised is a more fundamental one: that of the respect due to Ligue 1 itself. One is entitled to question the situation when the league sometimes seems to be relegated to second place behind other ambitions, however legitimate they may be.
"Racing Club de Lens remains committed to fairness, clear rules and respect for all stakeholders. Simple principles, for a fair and respectful French league."
