In a bizarre turn of events, the worst of it was suffered by the Red Devils' defender Lisandro Martinez. The Argentine received a direct red card for pulling the hair of the visiting team's player, Dominic Calvert-Lewin. You can watch the incident from the start of the second half at Old Trafford in the video clip included in the article. Incidentally, the visitors are leading 2:0 after the first half and are well on their way to securing a major victory in the battle for survival.
