Laying into him for the Walcott goal is silly and what makes it appear a witch hunt. IMO, he absolutely was NOT out of position. He was doing his job and preparing to run into the massive amount of space down that side if Arsenals defence.
We don't lose the ball in the middle and ball is played out to our left... and we are all saying how well he supports the attack. That comes at a cost. Opposition coaches aren't stupid and they know that when he pushes, as he clearly is instructed to, that's where the space is. That's not the fellas fault, it's a fault of either;
1. The tactics.
2. The teams implementation.
The press narrative of him always being out of position is out of all proportion compared to reality. Other players in the team need to cover his forward runs better if it's what Klopp wants from Moreno.
All that said, Moreno isn't and shouldn't be immune to criticism. He was needlessly rash for the penalty when there was no need to make a challenge at all imo.. should have just shepherded away from goal. He did make a couple of other small mistakes but really other than the penalty, if it was Clyne making them yesterday for examole, he wouldn't be getting crucified in the same way.
