Thanks for posting that link - I'd just read the piece and had come to post it on here.
I think it's a very good, sad and thought provoking article. One, fairly banal, sentence which took my eye was "Premier League clubs at a certain level really are that understocked with specialist knowledge." - this appears after the writer asks "Here’s a good question: why was McKay involved in this at all?".
I can remember very soon after Emiliano Sala's disappearance, Neil Warnock was asked about his relationship with Willie McKay and, from memory, his reply was that without McKay transfers like Sala's wouldn't happen - the inference was that McKay had almost made himself an essential part of certain types of transfers completed by British teams, but this has only happened because Premier League clubs that are raking in so much television money are unwilling to employ people who would make McKay and the role he plays obsolete.
