Hodgson want his squad to show their patrotism when the national anthem is played at games in Brazil
Hodgson said"You very rarely play against opponents and they haven't got their hands on their hearts and singing their anthem as loud as they can,"
"We made the decision very early on to do what every other team does."
"We are proud to be England players and, in my case, England manager, so when the national anthem comes up it's an obvious one for me that we sing it," added Hodgson.
"Perhaps we need to remind the players as the squad has changed so much. If they all sing it, I don't know. It's not something I've checked on. But I hope they will."
England flew out to Miami on Sunday as they continue their preperations for their World Cup opener against Italy in Manaus on 14 June.
England play two friendlies in the United States this week, facing Ecuador on Wednesday before playing Honduras on Saturday.
