Question - during the World Cup how do referees and players communicate with each other?

8. World Cup is easier than club, where the players on the same team all speak different languages

How do the players on AC Milan communicate with each other, much less the referee, when they come from France, the US, England, Ghana, Germany, and Italy? At least in World Cup, all the players on the same team speak the same language (more or less).

The answer was given above: most will speak sufficient "football English" to communicate in English.

(To be fair, most players in any European league are from that country - AC Milan players and refs mostly speak Italian to each other; the foreigners - like US player Christian Pulisic - learn enough calcio Italian to communicate with the ref, or, more likely, the ref speaks English well enough).
