Paris Saint-Germain manager Thomas Tuchel has criticised Neymar after the Brazilian's altercation with a fan at Saturday's Coupe de France final.
Making his first start since January, Neymar scored and provided an assist as PSG went 2-0 up against Rennes inside 21 minutes at the Stade de France.
A Presnel Kimpembe own goal and a Mexer strike soon after the hour forced extra time, during which Kylian Mbappe was sent off. Rennes then won on a penalty shootout (6-5) to complete a remarkable turnaround:

It was PSG's third successive season losing in the first knockout round of Europe's premier club competition.
Last season, PSG bounced back from their Champions League exit by winning a domestic treble.
They have already won Ligue 1 at a canter this term, but it is the first time since 2013 that PSG have failed to win either of France's major cup competitions. In January, Guingamp eliminated Les Parisiens in the quarter-finals of the Coupe de la Ligue, ending the side's 21-match winning streak in the competition.
