Inter Miami boss Javier Mascherano was spotted barking orders at his assistant manager over the phone after being sent off during their clash with Tigres.
With Lionel Messi watching on from the stands with an injury, Miami took on the Mexican side in the quarter-final of the Leagues Cup on Wednesday.
And the David Beckham-owned club got off to an ideal start, with star striker Luis Suarez putting them in front from the penalty spot with 23 minutes on the clock.
The remainder of the first half was a somewhat cagey and subdued affair - until Mascherano was left incensed by referee Mario Escobar on the stroke of half time.
