I think, you are onto something here... Regardless of personell and the specific game tonight, ETH doesn't seem to have an idea on how to inject control and/or security into our team. Not just by bringing player xyz onto the pitch but system wise. Was baffled more than once this season why he insisted on not going for a McFred midfield to see out a game. Some times it worked fro him, some times it didn't. Think he might be suffering from the same thing that Pep suffered from - trying to be too clever and an aversity to being pragmatic. I am sure the schedule and the rotation we haven't done in the last months and weeks also play a huge part but that will be something ETH has to show the ability to develop.
That is why so many have their issues with Bruno as a captain. He is passion and instinct player and a great one at that. But you have to pay a price. I'd love to look into the future to find out, if he will overcome that at some point in the future.
