A mass brawl unfolded between Manchester United and Barcelona on Thursday night after an incident involving Frenkie de Jong - a former United transfer target.
The chaos unfolded shortly after the hour mark when Aaron Wan-Bissaka fouled De Jong. As the Netherlands international was on the ground, United's stand-in skipper Bruno Fernandes smashed the ball at him - which led to a reaction from De Jong's teammates.
Several United and Barcelona players were involved in the scuffle - including Casemiro, who was sent off following a similar incident during a Premier League game against Crystal Palace earlier this month. There were no red cards handed out on the occasion.
