The whole "not without a replacement thing" should really apply to Armas too, because in a pinch you guys realize that Red Bull will almost definitely just continue further down the list cheap American coaches with limited to no experience, right?
They aren't going to fire him. Even if he loses the remaining five games and the team crashes out of the playoff race, my hunch is that management is more concerned about spending dollars for HR to interview new candidates and therefore will keep Armas instead of having to go through that process.
They are in total penny pinch mode right now. Any chance to cut costs, they are probably going to take it.
I bet they are loving the fact that the tarps up at each home game means they have to pay minimum wage to a few less ushers. Saves a few bucks there.
