That's the problem with people. they want to blame everyone even those who shouldn't really be blamed.
People are now talking nonsense about he left the midfield and drifted which is COMPLETELY false. He was staying quite deep and going forward mostly accordingly. We didn't lose because of our midfield, that's clearly nonsense. We lost because of our poor finishing and a poor error by the goal keeper. Herrera wasn't positionally suspect like some in this thread would make you believe, the game was thrown away because of something else which can't really be blamed on the midfield.
As for the goal, it's not like he wasn't anywhere to be seen, or vacated his position, he GOT BEAT by a nutmeg which happens to everyone and the rest followed. He couldn't teleport himself from getting beaten to stopping the goal.
All these talks about him drifting or roaming further leaving the midfield are lies.
