The summer heat could play a factor in Saturday afternoon's New York Derby.
With temperatures set to be in the high 80s with plenty of humidity at Red Bull Arena on Saturday, 90 minutes on the soccer pitch will be taxing on both teams.
"I think it has been good that we have been training in very hot temperature," Assistant Coach Bradley Carnell said after training on Wednesday.
Carnell said training in the elevated temperatures and humidity the last couple of weeks helped them "grind" out a win in Philadelphia.
"We have our preparation in the mornings and when we go out a little bit later, it gets a little hotter and I think that has prepared us well, especially in our last game against Philly," Carnell said.
