"Liverpool against Manchester United is about more than football, it’s about two cities which aren't far apart, and who have historically always been rivals," Rodgers told reporters. "It is arguably the biggest game in the world and for it to be here in the U.S., it's great viewing for them and magnificent news for the organizers.
"The most important thing is obviously about getting the players fit for the start of the season, but even winning in preseason creates that belief and mentality, and so it's very important."
Liverpool exceeded expectations last season as it narrowly missed out on the Premier League title, finishing second to champion Manchester City.
