Inter Miami’s Lionel Messi, Luis Suarez, Sergio Busquets and Jordi Alba supported another South Florida franchise Monday night as they attended the Miami Heat’s playoff game against the Boston Celtics.

Fresh off a 4-1 win this weekend at the New England Revolution, the Herons’ stars came out for a night in Miami with the Heat trailing 2-1 in the series heading into Game 4.

Messi has dominated MLS so far this season, scoring nine goals in just seven games as the Herons sit atop the Eastern Conference standings.

Last weekend, he put on a masterclass in front of more than 65,000 packed fans at New England’s Gillette Stadium to watch the football legend in action.
