Boca Juniors' players were involved in a sensational bust-up following a Copa Libertadores defeat as former Manchester United defender Marcos Rojo was seen punching a member of security.
Boca were left incensed after a goal from Marcelo Weigandt was controversially ruled out by VAR in the second-leg of their round of 16 tie against Brazilian side Atletico Mineirao.
The match went to penalties where Boca were defeated 3-1 and the evening soon descended into chaos as the Argentine side tried to break into the Mineirao dressing room before later clashing with police, who were forced to use tear gas in response.
