It makes you wonder what the interview and selection process for appointing the new manager was. Surely there might have been some questions along the lines of "what type of play will you be looking to adopt".
Perhaps they saw the instant success of Southampton adopting this style under Pochettino and thought this could be mirrored by their squad? Or maybe they are just daft?
When they first interviewed Mel they rejected him, ostensibly because he wanted to bring his own backroom staff in with him, whereas the club wanted to maintain stability and keep their existing coaches (exactly the same as when they interviewed CH and then appointed SC who, being coach rather than manager at Liverpool, didn't have his own assistants to bring with him). When WBA found themselves with no takers, they went back to Mel and he presumably withdrew his insistence on bringing his own people in. So Mel ends up trying to change things to his way of thinking while being assisted by people who were kept to ensure continuity with what they had before! Utter shambles, and why I said above that it would never have happened if Ashworth had still been at the club.
