I'm trying to explain to you that you can't blame the issues at the club on one singular person, especially when we continue to have the same issues season after season after season.
Either
A) Selles was in complete control of all scouting, data analysis, contract negotiations, fee negotiations and player sales, in which case why do we pay millions a year for a CEO, Head of Scouting, Data Analytics and a Contracts Manager when one man can do it all?
B) Selles was badly let down by the (lack of) structure of the club that would enable any other manager to come in and deliver results. The fact that the current club structure comprises of Wilder's mates that would be out of a job at any other club I'm sure is purely coincidental. Anyone at the club with any talent (Andrews, Lester, Hecky, McCall, Knill) have all been able to find gainful employment away from Sheffield United, something our current mob can't.
Lest we forget he started the season with a centre-back pairing for Bindon and Norrington-Davies, and a bench that had One, Marsh, Ukaki, Sasnauskas & Soumare. Do you think that was Selles' choice or was he badly let down by the club?
Clubs get managerial appointments wrong all the time. A most of them address it quickly and go again (Norwich, Southampton etc...). We're stuck in a doom loop because we've got a board to afraid or too incompetent to address the underlying issues with the club - and that issue is that we're run like the worlds biggest pub team.
