I'm worried about recruitment more than I'm worried about coaching. We had a lot of money to play with this summer and we have an expensively assembled mess to show for it. At least one of two things has to happen: (1) We need to revoke Koeman's veto power on incoming transfers, or (2) Walsh needs to be replaced.
We can survive bad coaching decisions but it's a lot harder to deal with the fallout from bad transfers. It's not just the initial waste of money but the money you need to spend to replace the players who didn't work out. We sunk £40-45m into Sigurdsson when we had already signed Klaassen and fresh blood at CB, LB, and CF were bigger areas of need. That's a huge fucking problem.
I know it's easy to play this game after the fact and that transfers are a lot more complicated than in FIFA/PES/Football Manager but just imagine how much better this squad looks if we do something like this:
one of Iheanacho (£25m)/Mounie (£11.5m)/Haller (£10m)
one of Maguire (£17m)/Wimmer (£18m)/Martins Indi (£7m)/Dragovic (loan fee)
a young left back like Charlie Taylor (tribunal)/Rico Henry (I'm guessing under £10m but hard to say since he didn't move this summer)
Williams takes a back seat, we have a natural centre forward to take the burden off of Rooney/Calvert-Lewin, and we get a talented left back to compete with and occasionally spell Baines. And we're short one player who doesn't seem to fit in anywhere in our first eleven.
I'm not trying to condemn Sigurdsson here because I do think he has genuine qualities. But we've spent a crazy amount to bring him into a set-up that doesn't suit his strengths while neglecting more pressing areas. That's way more concerning to me than overpaying for a good-not-great player.
