FC Dallas and Inter Miami fans clashed outside the stadium after their League Cup match on Monday.
Lionel Messi was once again the hero for his new club after he helped kickstart a comeback from 4-2 down at the Toyota Stadium.
The seven time ballon d'Or winner opened the scoring for Inter Miami, latching onto a pass from new signing Jordi Alba inside six minutes.
FC Dallas soon found their groove, though, scoring three goals before Benjamin Cremaschi pulled one back for Inter Miami.
An own goal from Robert Taylor restored Dallas' two-goal buffer before Messi took centre-stage once more, curling a free-kick into a dangerous area where Dallas defender Marco Farfan could only head into his own net.Five minutes later, the little magician produced even more Messi magic as he typically whipped a free-kick over the wall and into the top corner to take the game to penalties.
Messi and Sergio Busquets were on target from the spot as Inter Miami booked their place in the last 16, but some fans clearly didn't see eye to eye after the game.
A clip has emerged of both sets of fans fighting outside the stadium, with the cause of the brawl unknown. You can watch the footage below.Meanwhile, FC Dallas players were spotted taking pictures with Messi after their defeat, with the players unwilling to let their loss get in the way of a good photo opportunity.After the full-time whistle, Inter Miami manager Tata Martino waxed lyrical about his No. 10.
"We have the best player in the world. That can't be ignored. When we have our moments, the team is lethal," he said, before being asked where the team would be without Messi.
"This question always gets asked in the places where he is. Someone can bet on what Barcelona would've looked like without Messi, what the Argentina national team would look like without Messi or anywhere he's been.
"Fortunately, we have him, and today he once again showed he's a tremendously important player. The majority of times there's a free kick in this area, and I think only with him do you get the feeling that it's going to be a goal.
"A free kick usually is something where you think it won't be a goal 90 percent of the time, but when he has it, it's the opposite. You think it won't be a goal 10 percent of the time, but the rest it will be."
