I'm not sure I agree, there is lots to beat ENIC/Levy with that is justified, ex-players not so sure?
A lot of our ex-players, including ones that don't fudging care about football in general still seem to have a connection with the club and turn up, seem to have good relationship with club (see Bale, BAE as great examples), multiple ex players across multiple ex managers qualify.
I get GLC is frustrated with his time here, we were frustrated as well, him saying he was told he was part of the plans each season? he probably was, probably got injured but available or not, its on him to convince the manager (literally nothing to do with club regime). Dier was told multiple times to move on, Lloris also knew, and again similar to Dier was too picky about next step. I'd argue the club did huge favors to all the Hugo, GLC, Gil, Dier, Aurier, and others in recent past, we seemingly have walked back on the era of have to get money/back profit (Carrick/Modric/Berbatov era was different but even Modric seems to have a soft spot for us at times)
