"I will say if you're a man, you've got to react. Let's see how we're going to react. That's the way it is,'' Arsenal legend Henry told the New York Post.
"Hopefully we can react straightaway against Dallas. But somehow you've got to react. Nobody's going to care about a beautiful game or if we play better. We're going to have to react and soon.
"I'd rather play another team after the trip we had but it can also be good for us. If we have a good game against Dallas, that can lift our spirits.
"The way we started the game (Wednesday) was shocking. You can't start the game like that against Colorado. They showed us what it takes to be champions.
"I don't want to talk about the goals, I wish I had that much space and liberty to turn and control the ball or whatever. But no excuses, they wanted it more than us. They showed us why they have that little cup on their shirt because they are champions.''
