Without wanting to get into the finer details of your debate, I do feel that when it comes to footballing aspects they both should be respected - to an extent.
Yes you could rightfully say that neither are managing at a high level - well far from it to be fair - but they played at the highest level with the best calibre of player.
The stuff they're saying is neither new or controversial either: it was mentioned regularly when he was here and I am sure it will continue to be mentioned.
Personally, I feel that he's a great finisher but not an amazing footballer. At some clubs (us) that is often enough and he'll be happily lauded for his rate of goals.
Whereas, at other clubs the expectations and requirements are perhaps different, if not higher. I'd have him back here every day of the week, but they want better.
