Just been reading through the past pages...well.
To be fair to AM76, it's an issue of verification. I'm not POP's best friend (nor his worst enemy!) but if you tell me you can trust my information more than others because I'm qualified in the field, then I'm going to want to see verification before I proceed. If you want to truly learn something, every aspect of the process has to be impersonal: In a similar interest, when I post something in Italian / Italian source on the Rafa thread in a supposedly contentious issue, I ask the person with the contention to verify it for themselves. You need people to identify the information as purely as possible, so that they can trust it, go with it.
I've seen this stunt a few times, if POP is happy to share his credentials with the mods / has done so, the likes of Alan, Southern Pansy and VDM (who sadly doesn't seem to post much these days), and they confirm it, that's ok. If he can provide proof here, even better. Otherwise the I know routine is laughable. POP has been posting good information on the basics / generalities of football ( I remember postings on the defensive units particularly) way before any of the recognition now so it's useful, don't take it as me having a go, but the quality of coaching is in the details. It's the right step to ask for proof / verification before you proceed.
PhaseOfPlay has the right to remain anonymous. If you don't want to take his thoughts, place him on the ignore list.
I won't lie. I would love to know more about him personally and his coaching. He's a fascinating, articulate and impressive man. But I never will know much, nor do I have the oligation to know either.
Just read his posts, give your thoughts and have a debate with him if you want. You may not know his name, but he knows a damn more about football than most of us posters, and you only have to see his posts/threads. You will also learn a lot through his eyes and mind about the profession.
