This Club World Cup match was the first of eight to be played in the city over the next two weeks, attracting soccer fans from all over the world.
Ahead of Monday night's match, Vivianne Marcal, of Salvador, Brazil, told Action News she was "so nervous, so excited" to watch Flamengo play in the U.S.
She has been a fan of the Brazilian soccer team all her life.
Earlier in the day, fans of both teams rallied outside the Philadelphia Museum of Art. Some took their pictures with the Rocky statue, while others spent time soaking in the sights of the city.
Both fan bases also made stops at Chickie's and Pete's in South Philadelphia ahead of the game.
Slim Mokni, who is from Tunisia, said, "It's great to be here, honestly... You get to know other people from other countries, other cultures, great atmosphere."
For the Falkenstein family, Monday night was the start of a week of celebrations. Debora Falkenstein is originally from Brazil, so she and her husband, Ed, are hosting Flamengo fans at their home in South Jersey all week.
She told Action News, "It's amazing because we know how our fans are here - the Eagles fans, the Phillies. So, to bring Flamgeno, like the biggest team in Brazil, to Philadelphia - it's like, we can't believe it."
The Club World Cup features 32 of the best professional club teams around the world.
The General Manager of the Courtyard Philadelphia in the Navy Yard said these matches will offer a big boost for the city.
