MLS round-up: Gonzalo Higuain embroiled in scuffle after penalty miss on Inter Miami debut

Gonzalo Higuain's MLS debut was one to forget as the new Inter Miami forward missed a penalty and was involved in a scuffle during their 3-0 defeat to Philadelphia.

Miami were already two goals down against in-form Union when Kacper Przybylko's handball gave the ex-Juventus forward a chance to halve the deficit, but after ballooning his penalty over the bar he was involved in a heated argument when confronted by a number of the home players.

Anthony Fontana put the hosts ahead against the run of play before half-time, but despite Miami's continued dominance, they fell further behind to Ilsinho's close-range finish after 70 minutes, minutes before Higuain's miss from 12 yards.
