Christophe Galtier's Lille had only lifted the top-flight title in France once since 1954 – securing their last triumph when Mbappe was 12 years old – and are thought to pay their entire squad a salary that is little more than half of Neymar's reported annual earnings of around $64 million.

While PSG owners Qatar Sports Investments might have expected a fourth successive title to be little more than a formality for a side with ambitions of Champions League glory this season, the expensively-assembled European giants have faltered badly at times, failing to win 12 of their 38 league matches and losing eight times along the way.

Never one to shy away from drama, Neymar missed a penalty and was booked for dissent in the first half at Brest, who finished just a point above the relegation zone.
