True - Only part of that is down to the manager though even if you attribute sole responsibility of transfers to him, we still had a bad overall squad when he took over. Antony was way overpriced, I don't really know what drove that but maybe ETH fell out with Sancho early days and wanted anyone but Sancho (we didn't have a proper RW as well) - a bad decision regardless. Mount could've been delayed for other priorities, and was a mistake. With that 140M or so pounds, we should've signed a starting RCB and a starting CDM + two decent squad options for around 100M total. Case also is kind of a mistake in that sense too, we should've considered a younger profile player there - I thought he'd have gone for Edson Alvarez out of the Ajax team that summer instead of Antony tbh and was shocked when he didn't.
Also, while ETH has a say in transfers, do we actually know if he has a say in the fees? My understanding is that Murtough is the one that negotiates while also having the ability to veto? I did read somewhere that even Ten Hag was surprised at Antony's transfer fee (albeit from the English media which I don't usually trust). I'm not saying this to pin the blame on Murtough, but these wouldn't have been one-sided decisions. Manager is still at fault for these mis-spends of course although maybe not solely responsible.
I agree mistakes have been made but this squad still needs open heart surgery because our squad options especially are rubbish - From previous eras, Maguire, AWB, Mctominay, Sancho, Greenwood and perhaps also Victor all need to go for a variety of reasons. As for the starting 11 we've replaced 6, retained 5. 2 of those starters (Varane, Case) need replacing for younger players on more sensible salaries as well.
Whether it's ETH or another manager, I hope they get it right from the negotiations side and stop overpaying for players - part of that will be to start moving really early on transfers and maybe have a larger team negotiating multiple transfers at once rather than one at a time. This whole Murtough going there personally to negotiate transfers one at a time thing is so early 2000s' David Gill
