SOCCER: Paris FC give neighbours PSG a 'slap in the face' in French Cup upset

Paris Saint-Germain midfielder Senny Mayulu described their surprising 1-0 defeat to Paris FC on Monday as a "slap in the face," after the defending French Cup champions were eliminated in the round of 32 by their city rivals.

Just four days after securing their fourth consecutive French Super Cup, PSG were humbled at the Parc des Princes by Paris FC, who returned to the French top flight this season after a 46-year absence.

The decisive goal came in the 74th minute from former PSG player Jonathan Ikone.

"We dominated the game, but unfortunately we couldn't convert our chances," Mayulu said. "It's a defeat, but we're going to bounce back. We want to regain first place in the Ligue 1 championship. We’ll give our all in training and do everything we can to win the remaining competitions."

Ikone, a product of PSG's youth academy who made his senior debut with the club, refrained from celebrating his goal against his former team.

"No, no celebration. They gave me everything," Ikone said. "I’m happy to score, but I respect the club that made me. We defended well and scored the goal we needed to win. I hope this gives us momentum for the championship too."

Paris FC currently sit 15th in Ligue 1, four points above the relegation zone, while PSG are second, just one point behind surprise leaders Lens.

PSG manager Luis Enrique acknowledged the result was harsh given his side’s dominance.

"It's a competition we love, and we have to accept it," he said. "If I have to lose matches, I’d like it to be this way." -Reporting by Rohith Nair in Bengaluru; Editing by Peter Rutherford/Reuters
