I'm not saying there weren't any moves to make, at all. Of course he could throw on anyone for anyone. But, he had a couple of young wingers, an attacking midfielder, a striker, a right back, and a center back. And, all (other than the injured right back) lacked experience. He could have done some late reshuffling in the match and taken out Hitz, moved Heits to mid, brought in Hibbo to rb. But, that would've meant shaking things up, maybe too much at the time.
I'm not saying he was right or wrong. I just can understand there not being a clear logical move to make.
