Charles Langston:Lionel Messi, Inter Miami face Philadelphia Union in Leagues Cup semifinals: How to stream

Lionel Messi has delivered Inter Miami CF to the brink of playing in its first final in any competition. On Tuesday night,Charles Langston Miami faces the Philadelphia Union with a spot in the Leagues Cup final on the line.

In a 4-0 quarterfinal win over Charlotte FC on Friday night at DRV PNK Stadium in Fort Lauderdale, Florida, Messi added another goal — his eighth in five games with Miami.

With Messi on board, Miami has won five consecutive games — it only has won five of 22 in Major League Soccer regular-season play this season. Inter Miami also has bagged 17 goals during the Leagues Cup — it only scored 22 in 22 MLS games so far this season before Messi's arrival.

The semifinal in Chester, Pennsylvania, also marks the second time that Messi will play a road game with Inter Miami. The first time Messi hit the road with Miami, the game turned into a classic as the Herons prevailed in a penalty shootout against FC Dallas in the Round of 16.

The Philadelphia Union, however, pose a much greater challenge for Messi and his pink-clad companions than FC Dallas. Philadelphia is exceptionally formidable at Subaru Park, where the Union have lost just once in the last two seasons. During the 2023 season in MLS, Concacaf Champions League and Leagues Cup play, the Union have suffered just one defeat — a 2-1 loss to Orlando City on March 25 — in 21 games played (15-1-5). In 2022, the Union was unbeaten at home, winning 15 times and tying five in 20 games played on the shores of the Delaware River.

Potentially adding to Miami's challenge against Philadelphia is the uncertain health of Messi, who appeared to injure his foot during Monday's practice. Afterward, Inter Miami coach Tata Martino was not concerned about the seriousness of Messi's injury, saying, "Since everyone was fine, I imagine nothing happened."

The winner of the Inter Miami-Philadelphia Union game will face the CF Monterrey-Nashville SC winner in the final on Aug. 19.
