FWIW, if this turns out to be an external appointment then the conversation regarding how it took so long is going to be interesting. Desperate because no one fancied the working conditions, thorough because they wanted to be sure and get it right or anything else you can think of.
Who knows. If the club have every confidence in Mad Gav in the interim role, then they could just be testing the market in terms of a permanent appointment.
It's possible that the labour pool might need to adjust in terms of working under a data driven approach as more clubs start to run with it.
If a solid infrastructure & model is in place then head coaches are more expendable as shown by Watford's approach.
We are some way off being in a position to do that, but the days of placing the recruitment budget & decision making in the hands of one individual are long gone I suspect.
