Last week, Real came from behind two defeat Houston Dynamo 3-2 but this week the spark wasn't there which let Kreis down.
"I thought there would be something break our way that would lead to some confidence, some momentum and some emotion from our players," he said.
"We had some chances there after that second goal where we were in their box with some chances to score but we don't take them.
"Maybe if one of those things happen, maybe the emotions and the momentum shift our way and maybe we have a good reaction. We need to show a little more fight to get to that point.
" at the moment, it's hard to not to feel disappointed. I'm never defeated," Kreis added.
"There are points on the table that will get us in and I'm fighting for them. I'll only have players on my team that will fight for it as well.
"We're going to be watching reactions of players. If there are guys that aren't fighting for it and don't believe, they'll be off the team very shortly."
