I did see your other post, don't really agree.
Yes Olver played along time ago relatively speaking, but it has zero to do with Glover's performances.
Before I continue I would like to put it out there I got no idea if Olver is bad coach, and therefore cannot confirm if he is a brilliant coach either, but surely, to say that he's unable to teach/coach modern goalkeeping techniques because he retired a few decades ago is wrong.
The bloke has been involved in the game, obviously has numerous coaching badges and has been studying analysing and above all coaching for a very very long time.
I'm putting it back on Glover, he is at minimum 95% responsible for his own performances.
Glover would have had at least 15 different coaches over his journey to become a professional and all of them would have been responsible for his development but none of them have ever been responsible for his performances.
He is the one that at the end of the day that decides to come, to stay, punch, catch, kick long short.
Imo Glover is the problem not Olver.
I'm also undecided if last season was an aberration and he played at a level above himself and this season is his true level or he is just in bad run of form and will come good again.
