Paris St-Germain will not open their Ligue 1 title defence at home after officials determined that the Parc des Princes pitch has been left in an unsafe condition following this summer's extreme heat across France.
The reigning champions were originally set to host Rennes in Paris on Sunday, but the fixture has now been reversed, with the match instead taking place at Rennes' stadium in Brittany. The decision was made by the Ligue de Football Professionnel (LFP) after inspectors examined the playing surface at PSG's home ground and concluded it was not fit for competitive action.
According to the LFP, the assessment found that conditions at the Parc des Princes "did not allow the match to be played under satisfactory conditions, particularly with regard to the safety and physical integrity of the players." The governing body's statement made clear that player welfare was the primary concern behind the switch.
PSG confirmed that the pitch will be fully replaced before the club's next scheduled home game, a Ligue 1 clash with Monaco on 4 September. In a statement, the club said it "fully understands the inconvenience caused by this change" while describing the circumstances as an "exceptional situation" beyond its control.
The root cause of the damage lies in the extraordinary temperatures that swept across France this summer. The country recorded its hottest day ever on a nationwide average basis on 24 June, with the mercury in Paris climbing to nearly 41C. Roughly half of France was placed under a red heat alert as the extreme weather took hold, straining infrastructure and public health systems alike.
The human toll of the heatwave was severe. Figures showed that deaths recorded across France between 22 and 28 June rose by 2,025 compared with typical levels — an increase of nearly 30%. In the Paris region specifically, mortality rose by 62% over the same week, underlining just how intense the heat spell became in the capital and surrounding areas.
This summer's unusually high temperatures have affected much of western Europe, with France among the countries hit hardest. Wildfires broke out in several regions as the dry, scorching conditions persisted for weeks, adding further strain to a season already marked by climate-related disruption.
PSG's situation is not an isolated case in European football. Earlier this month, Spanish side Celta Vigo were forced to postpone their own La Liga season opener against Osasuna after their pitch at Estadio de Balaidos was affected by a fungal outbreak. The fungus reportedly took hold after temperatures at the stadium failed to drop below 25C for more than three weeks, creating conditions that allowed the growth to spread unchecked across the playing surface.
Together, the incidents in Paris and Vigo highlight a growing challenge facing clubs and leagues across Europe, as prolonged periods of extreme heat increasingly threaten the condition of natural grass pitches and, by extension, the scheduling of top-level fixtures.
For now, attention turns to Brittany, where Rennes will host the champions in a reworked fixture, while PSG prepares to overhaul its home surface in time for the visit of Monaco next month. Whether this summer proves to be an outlier or a sign of things to come may determine how clubs approach pitch maintenance and fixture planning in the years ahead.
