Inter Miami defeated Columbus Crew with a brace from Lionel Messi on Wednesday night (Oct. 2) to mathematically clinched the Supporters’ Shield, as the team with most points during the MLS regular season. With this triumph, Messi and The Herons could win a place in the upcoming 2025 Club World Cup, which will be held by the United States.

30 out of 32 teams have already been confirmed for the tournament. The two remaining spots will be determined by the winner of the 2024 Copa Libertadores (in case the winner if already qualified, it will be determined based on the points table), and the other one will be a club from the host country.

However, the MLS is considering two options to award the spot: it will be either for the Supporters’ Shield winner (in this case, Miami) or the winner of the MLS Cup. If Miami indeed earn the spot, Messi could win his fourth Club World Cup title, after he clinched three with Barcelona (2009, 2011, 2015).

The MLS hasn’t confirmed their plans but, according to reports, it would be determined in the upcoming weeks. Meanwhile, there is already one MLS team confirmed to participate in the tournament: the Seattle Sounders, who will be competing after their 2022 historic win in the CONCACAF Champions League.
