KANSAS CITY, Kansas City — There was plenty to be concerned about the Red Bulls’ 2-0 loss to Sporting Kansas City Wednesday.

Yet, Red Bulls head coach Jesse Marsch refused to talk about any of the problems that led to the team having its three-game winning streak snapped.

Perhaps he didn’t want to take an hour to talk about the team’s problems during a difficult 90 minutes.

“I could focus on negative, but I’m going to focus on positive,” he told reporters at Children’s Mercy Park. “The positive is for me that Amir Murillo played in the game and played quite well, which shows that he can handle a game like that. A big step forward for him.”

Murillo, a Panamanian international defender, made his debut at right back.

His focus then went to forward Fredrik Gulbrandsen’s performance.

“Fredrik Gulbrandsen until he had to come out, I thought put a lot into the game, won a lot of little duels and I thought was a little bit unlucky not to get us the lead at 1-0,” he said. “So his performance too continues to show that’s someone we can count on and then Aaron Long for me. It’s a shame that Dom Dwyer got two goals because Aaron did so well against him, I thought. He won a lot of duels and battles and continues to show he can handle the big responsibilities within the team.

“Then there’s other guys like Luis [Robles] and Felipe that you know you can count on. So we’ll get everything right and make sure that we’re ready for Saturday.”

That would be against the Philadelphia Union in Chester, Pa. Saturday.

Due to the fact the Red Bulls are in the midst of playing three times within an eight-day span, Marsch decided to rest several regulars against a team that played its first-team lineup for the fourth consecutive match Wednesday night.

“We knew going into the game that it was going to be about physically being up for the challenge,” Marsch said. “Obviously we had to play a make shift lineup to get through this week the right way and go down to Philly and get what we think are going to be some important intra-conference points.

“We know that is always a challenge because Philly, as much as they’re having a tough year, they always play well against us. They’re always prepared and they’re desperate, so it’s not going to be easy, so we’ll have to figure out which guys from here can regenerate and we’ll have some fresher legs ready to go for that one.”

The Red Bulls (5-4-1, 16 points), in second place in the Eastern Conference, will meet a winless Philly side (0-4-4)  that is mired in 11th and last place in the conference. In other words, the Union hasn’t won at home (0-2-2).

Asked when he would start focusing on the Philadelphia match, Marsch replied, “Right now. So, we can’t mope about the last game. This game, we’re obviously disappointed but we’ve got to figure out a way to regenerate and refocus and go after a big game in Philly.”
