Profit is one word to use. Sustainability is another. It's not even twelve months ago where it turned out it was promotion or we're probably fucked, so I don't think it's necessarily fair to report like this has been. Where we have spent, it's been on for all intents and purposes a loan (Archer), getting younger at positions where we needed to get younger, but would probably take time to get up to PL speed (Traore, Trusty, Souza, Slimane), and an effective like for like swap which spends no money but improves the contract situation and arguably improves the side (Hamer for Berge). All these seem to me to be somewhat joined up to try and leave us in a stronger position if (now when) we did return to the Championship than when we left it.
Where the criticism can be laid, however, is the complete underestimation of how much of a lynchpin Ndiaye was, and that he shouldn't have been sold for anything apart from silly money (and what we got for him, by whatever report you want to read, is nowhere near that). This was said at the time by myself and others and isn't hindsight after one point in ten games. Dropping from having a creative option to having no creative options was a completely foreseeable consequence, and it's no surprise that the team has looked a lot worse as a result
