The El Tráfico derby has become bitter in recent times, with clashes between Los Angeles cross-city rivals LAFC and LA Galaxy having been some of the most fierce in MLS - and the most recent round of tension was started by a Lionel Messi-inspired celebration.
Of course, the fireworks and controversy that has accompanied the fixture in recent years also is likely to increase the intrigue surrounding the July 4 game between the two rivals. This is the first time the two teams have faced each other since a tense encounter in the US Open Cup back in May which saw the Galaxy run out 2-0 winners.
Two of the standout names from the clubs were involved in some petty joshing in the knockout game, with former Juventus star Giorgio Chiellini having criticised opposition player Riqui Puig following the Barcelona academy graduate's goal in the fixture. The Italian veteran was particularly irked by the 23-year-old's celebration following his strike, which put the result beyond doubt.
