Mascherano insisted that what appeared to be a heated argument was nothing more than a tactical discussion in the heat of battle.
"There's no problem with Leo," he insisted. "It came out in the press that he was challenging me, which is really nonsense."
The former Liverpool and Barcelona man went on to explain that the team’s midfield spacing had broken down after Chicago dropped back, making it difficult for Miami to move the ball between the lines.
He added: "We were talking about Chicago's low block. If you look at the game, after their first two goals, they played a very low block, and there was little space to find between the lines. It was a space problem, because they had dropped back very well, and it was very difficult to find space between the lines. It was a problem that I saw and that we tried to talk about in the locker room."
