Boca Juniors - Benfica

I am going here with a tendency towards Brazilian clubs. So far, all of the clubs here are receiving a lot of warnings and usually end up with at least two warnings per game. Even though Flamengo and the Brazilian league tend to receive very few warnings, this is a completely different tournament with different opponents, so anything can happen. The referee is Dutchman Makkelie, who has been known to give out an average of 3.2 cards per game in the Eredivisie league this season, but in international tournaments, the average rises to 4.3.
