The CONCACAF Champions Cup pits the best North American and Caribbean teams against each other in a knockout tournament.
Mexican teams have traditionally dominated the tournament, winning 39 trophies in the competition's 62 years of existence.
But have any teams from MLS, which began play in 1996, ever won the tournament?
Three MLS clubs have won the CONCACAF Champions Cup: DC United in 1998, LA Galaxy in 2000, and Seattle Sounders in 2022.
DC United won the first two championships in MLS history, winning MLS Cup in 1996 and 1997. They couldn't make it a third consecutive MLS Cup in '98, but they managed to bring home another title.
DC directly qualified for the eight-team knockout round due to winning MLS Cup, and they faced Trinidad & Tobago-based club Joe Public FC in the first round. The team from the nation's capital took care of business on home turf, winning 8-0.
In the semifinals, DC United met Mexican side Club Leon and won 2-0 in DC thanks to two goals from Roy Lassiter.
That win set up the final against Toluca at DC's Robert F. Kennedy Stadium, which DC United won 1-0 thanks to a 41st-minute goal from George Pope.
Lassiter took home the tournament's top scorer and MVP awards, and he made the team of the tournament along with four other teammates: Goalkeeper Scott Garlick, defenders Jeff Agoos and Eddie Pope, and midfielder Marco Etcheverry.
LA Galaxy finished as the MLS Cup runners-up to DC in 1999, which granted both teams automatic qualification to the 2000 CONCACAF Champions Cup knockout stage.
Things weren't smooth for the Galaxy in the quarterfinals and semifinals.
They met Honduran team Real Espana in the quarters and escaped with a 5-3 penalty shootout win. Their semifinal match against DC also went to penalties after a 1-1 draw, and the Galaxy won the shootout 4-2.
In the final against Honduran side Olimpia, the teams scored three goals between the 30th and 40th minutes, giving LA a 2-1 halftime lead. Olimpia scored the equalizer in the 51st minute, but Ezra Hendrickson scored the 78th-minute winner to bring the CONCACAF Champions Cup back to the States for the second time in three years.
In 2022, an American team had not won the CONCACAF Champions Cup in more than two decades, and Mexican teams had won it every year since 2006.
But five MLS teams qualified for the 2022 edition, and four won their first-round match. The Seattle Sounders snagged the last spot available for American teams as they had the best record among non-qualified MLS teams in the previous season.
The two-legged, home-and-home matchups played a pivotal role in the Sounders' run to lift the trophy. They did not lose at their home stadium, 68,740-seat Lumen Field.
In the round of 16, the Sounders beat Honduran team Motagua 5-0 on aggregate — drawing 0-0 in the first leg on the road and winning 5-0 in the home second leg — setting up a quarterfinal match against Mexican team Leon.
The Sounders took care of business with a 3-0 first-leg home win that included two goals from Fredy Montero. The second leg was a 1-1 draw in Mexico, which Seattle led 1-0 for almost the entire second half until a stoppage-time consolation goal for Leon.
Seattle moved on to play fellow MLS team New York City FC in the semifinals, and the Sounders once again set the tone in the first leg at home with a 3-1 victory. A 1-1 second-leg draw was enough for Seattle to advance to the final.
The Sounders met Mexican giants Pumas UNAM in the final, which was another two-legged matchup. A goal in the ninth minute of second-half stoppage time from Seattle attacking midfielder Nico Lodeiro salvaged a first-leg draw in Mexico, and the teams went to Seattle for the decisive second leg tied 2-2.
Seattle, as usual in this tournament, defended its home field effectively. Raul Ruidiaz opened the scoring just before halftime and doubled his team's lead in the 80th minute. Lodeiro put the icing on the cake with an 88th-minute goal to seal the win for the third CONCACAF Champions Cup trophy won by an MLS club.
Sounders goalkeeper Stefan Frei won the tournament's Golden Glove for best goalkeeper and Golden Ball for best player. He kept four clean sheets and made the team of the tournament with six other Sounders: Defenders Nouhou Tolo and Xavier Arreaga, midfielders Jordan Morris, Cristian Roldan, and Lodeiro, and forward Ruidiaz.
