Not worried at all.
In fact it's better if USA's momentum starts rolling in the 2nd Half instead of scoring before halftime and having them re-focus. Our offense is looking great and I have no doubt as time goes on and fatigue starts kicking in we'll take over even more. First through ball instead of long shot and we're back in it. Even going down 2 early in the 2nd half I'd fancy our chances of a comeback.
All we need is a draw TBH, and if we lose there's not a problem, I think we have more than enough to give Germany problems.
but... I believe that we will win (not a chant, I actually do think, rationally, we got this)
