A lot has been made about the lack of genuine quality striker but the upper management of the club including the directors, plushWalsh and Koeman all made a massive error in not identifying how defensively frail we are.
I know having a better striker and more of a goal threat would make us less likely to concede goals but we have had Steve fucking Watson playing as our main striker in the past and we didn't look this bad defensively.
Our (outfield) defence is a shambles and there is a real lack of leadership despite the relative experience of our senior defenders.
Jags, Williams and Baines all need to be replaced sooner rather than later and aside from Keane, who does not look like he has the experience or leadership skills yet, we made no planning for the short to medium term future here aside from buying Martina as a stop gap.
I don't think this responsibility falls directly on Walsh, I think it should have been the collective responsibility of Walsh and Koeman and the board to plan player recruitment for the short, mid and long term. But we did none of the this in the defensive department. We have bought talented exciting youngsters but we need to identify and recruit defenders who are in or coming into their prime who will take us into the upper echelon of clubs.
