Igor Jesus scored the winning goal as reigning South American champions Botafogo stunned newly crowned UEFA Champions League winners Paris Saint-Germain in FIFA Club World Cup Group B on Thursday.

Paris Saint-Germain, one of the favorites in the 32-team tournament, had cruised past Atletico Madrid 4-0 in the first round last Sunday, while Botafogo defeated the Seattle Sounders 2-1.

Jesus netted a solo goal in the 36th minute, capitalizing on a deflection off a defender. The Brazilian club then held firm through a wave of second-half attacks from the French powerhouse, handing Paris Saint-Germain its first loss since May 3.

Paris Saint-Germain registered 16 shots but only two on target, while all four of Botafogo's attempts were on goal.

"A lot of people wondered, but we showed how strong Botafogo is," Jesus said. "It was a difficult game, and we had to defend well, and we did our job and scored a goal.

"We're really happy. We knew how important this game was. One team was the champion of the Champions League, the other team was the champion of South America," added Jesus.

Paris Saint-Germain head coach Luis Enrique said it's normal for any team to lose matches in a world-level tournament. "This competition is very intense and difficult. Every team is motivated, especially against our team. I sometimes think our team struggled against their defense. I think Botafogo is one of the toughest defensive teams in the tournament."

Botafogo now leads the group with six points, three ahead of both Paris Saint-Germain and Atletico Madrid. All four teams, including the Sounders, who have lost both matches, remain in contention for a spot in the knockout stage.
