Foxborough used to be one of the favorite sites for U.S. matches and many of the team's most famous clashes were played there. But when Gillette Stadium ripped out its grass in favor of artificial turf in 2006, the U.S. team stopped playing there with regularity. Their Gold Cup match against Haiti this summer was their first match at the venue in four years, but now they're going to return for their second match at the stadium in just three months.
There is no word yet on what the playing surface will be for the friendly, but it's safe to assume that temporary grass will be laid down over the venue's turf. Brazil almost always insists on a natural surface.
Brazil are obviously one of the biggest teams in the world and should bring a giant crowd to the 68,000-sat Gillette Stadium. The Selecao will provide the Americans with a stiff test, but this isn't the dominant Brazil of years past. Not only were they embarrassed by Germany at last summer's World Cup, but they've crashed out of the last two Copa Americas in the quarterfinals and are overly reliant on Neymar. Brazil are not one of the best teams in the world right now.
The U.S. has already scheduled a friendly against Peru in Washington, D.C. on September 4, so this will give them two friendlies in the FIFA international window and they will be the Americans' first matches after the Gold Cup. If the U.S. wins the Gold Cup, they will then schedule two more friendlies in October, but if not, then they will have a playoff for CONCACAF's spot in the 2017 Confederations Cup that month. World Cup qualifying begins in November.
