Yes, this.
It's the same problem / answer when TAA plays. He ventures forward a lot and is not the best defensive fullback in the world so he needs the team to give him the right support so that we don't get punished.
Henderson at his best is good at providing that cover. Today he was rubbish, as was Fabinho. I guess you could argue that they were up against one of the best midfields in the game right now but they should've been better than they were.
As we knew in the summer, we're a quality midfielder short.
