Barcelona suffered its first defeat of the season Tuesday, losing 4-2 to Paris Saint-Germain in the third round of the UEFA Champions League league phase.

Barcelona entered the match at Parc des Princes in Paris having won all 11 of its competitive matches this season — nine in La Liga and two in the Champions League.

PSG, meanwhile, extended its perfect Champions League start to three wins, scoring 14 goals and conceding five to move alone atop the league-phase standings.

The defending European champion also extended its winning streak in all competitions to seven matches, including four straight league victories.

Barcelona held a slight edge in possession, 53% to 47%, but PSG had the advantage in shots, 22-18, and shots on target, 15-5.

PSG suffered an early setback when Ballon d‘Or winner Ousmane Dembele was forced off in the 20th minute with hamstring discomfort.

Barcelona also lost Dani Olmo to injury in the 27th minute after he experienced discomfort in his ankle.
