Lesser/EPA-EFE Nov. 11 (UPI) -- Lionel Messi said Inter Miami will get ready to "come back stronger next year" after the Herons' upset loss to Atlanta United in the first round of the 2024 MLS Cup playoffs. The Argentine striker, who registered a goal and assist in the best-of-three game series, also cited the Herons' growth this season, when they led MLS with a record 74 points.

"Thanks to all the people who joined and supported us. "Now let's get ready to come back stronger next year."

Their first-round foes bounced back with a 2-1 victory Nov. 2 in Atlanta. Midfielder Matias Rojas gave the Herons a 1-0 lead with a 17th-minute score in the series finale Saturday in Fort Lauderdale, Fla. Forward Jamal Thiare answered with two scores just minutes later to give Atlanta United a 2-1 lead at halftime. Messi found the net with a 65th-minute equalizer, but midfielder Bartosz Slisz scored a go-ahead goal for the visitors in the 76th minute. Saturday's result marked the greatest playoff upset, points-wise, in MLS history -- as the Herons were 34 points better than Atlanta United in the regular season. "We had good times and bad," Herons manager Tata Martino told reporters, when asked about the record-setting 2024 campaign. "When you think about where we were last November, we made a lot of progress. "But if you think about our expectations that we had for these playoffs, we obviously fell short."
