The Red Bulls are struggling at the moment, but Union coach John Hackworth is preaching caution ahead of the I-95 showdown.
"This is a really important game for us," Hackworth said at press conference earlier this week. "We can't go in there in any other mentality other than the one we approached Colorado and New England.
"We know that early in this year, a lot can change, and we have to be very humble. We have to understand our strengths and know our weaknesses and try to go up to New York and play a very good opponent, and see if we can get a result."
Hackworth's "humble" comment was echoed by forward Sebastien Le Toux. The Frenchman spent the second half of the 2012 season with New York, scoring one goal in 14 matches. He also cited Philadelphia's superior togetherness as an edge the Union might have over the Red Bulls.
"Everybody now is ready to get another result away,” Le Toux said on Wednesday. "We have put ourselves more confident going on the road this year, because we got our first win in Colorado.
"Now we know we can win, but we still have to be careful and don’t be too confident and be very humble, because I think New York is probably a better team on the paper than us. But maybe we can do a result over there, because maybe we play more as a team than they are doing right now."
