I get what you’re saying, but part of me thinks it can be argued that the 18 yard line as defensive line was an attempt to take a cognitive load off of the players. That line doesn’t change, so if the players organise around that, it should reduce error.
I also think that Bowen goal was just a Ben Davies error. Simple as that. He messed up. But he’s our 5th choice centre back for a reason, and played a lot more than 5th choice centre backs usually do. And I think part of the reason we conceded so many goals was the relative lack of games we actually got anything approaching our first choice 11 on the pitch.
I understand too that we conceded a lot of goals under Ange, but I just would have loved to have seen his system in its intended final form. Because when that happens, it was about squeezing the opposition in their half and not giving up too many chances at all. When a team is unable to actually play the way they have been built and trained to play, there are always horrible stats in goals conceded and scored. And then it looks like the manager is missing something obvious. But usually it just requires getting players back fit and things start falling into place.
But yeah on Romero specifically, I agree we were using the 18 yard line. I’m just not convinced it was beyond the ability of top level footballers to carry out. I also don’t know exactly why we were using it, but a top level manager trying to win games probably had a reason. Maybe it was precisely because we didn’t usually play with a double pivot, and so we would be vulnerable to the slips in behind. And this was a way to mitigate that while allowing our players to take up the offensive positions we want them to have in possession?
