PSG and St Etienne players clashed during the Coupe de France final.

A horror challenge on Kylian Mbappe reduced the star to tears and sparked a mass brawl during the Coupe de France final between Paris Saint-Germain and Saint Etienne on Friday night.

The Ligue 1 champions had already taken a 1-0 lead at the Stade de France when Neymar put Thomas Tuchel's side in front, celebrating with the small section of PSG fans allowed inside the stadium.

But with just 31 minutes gone the game took a sour turn when Mbappe was wiped out by veteran defender Loic Perrin, who was making his final appearance for the club with Arsenal loanee William Saliba unavailable for selection.

The incident sparked ugly scenes on the pitch after the players became embroiled in a 21-man brawl, with players from both benches all getting involved.

The referee Amaury Delarue initially awarded a yellow card for the tackle but, after a lengthy VAR review, deemed the challenge worthy of a red card and Perrin received his marching orders.

PSG duo Mitchel Bakker and Leandro Paredes were handed yellow cards along with St Etienne's Romaine Hamouma for their roles in the melee.

After the French referee had completed his assessment of the incident, substitute Marco Verratti was also shown a yellow card.

Mbappe required medical attention on the pitch after suffering a nasty knock to his ankle and after it became clear he could not continue, the 21-year-old left in tears as he hobbled down the tunnel.

That could cause some concern for PSG, who are scheduled to play Atalanta in the Champions League quarter-final first leg on August 12.
