The Club World Cup brings a certain level of excitement for soccer fans. But some are feeling uneasy about the level of security at match venues. U.S. Immigration and Customs Enforcement agents doubling as security for major sporting events isn’t uncommon.

In Miami, when asked about concerns that ICE agents would be at Saturday’s Club World Cup opener looking for people who are in the U.S. illegally, FIFA president Gianni Infantino said he didn’t “have any concerns about anything, in the sense that we are very attentive on any security question.”
