Freddy,
I have exactly this debate with fellow Villa fans. I think no one person is greater than the club and we should also strive to get the best we can whether that is a player, a manager or a CEO or any other position at the club. Personally, I feel Dean Smith has taken Villa just about as far as he can. I would love to see us getting a manager like Pochettino and if we could get him I would sack Smith in the morning. However, it may prove impossible for Villa to attract a Poch type manager and if that is the case then I am happy to stick with Smith. I think where Sheffield United are currently in their development, that CW is the best manager for you. If he stabilises the club as a midtable PL team then it may be time to look to get a 'better' manager. I look at the teams in the PL (outside the of big boys) that have modern, attacking style managers: Nuno (Wolves), Hasenhuttl (Saints), Potter (Brighton) and Bielsa (Leeds). These teams are all developing on the pitch and all look to be heading in the right direction. They are playing the style of football I want to see my team play. I think the other manager like Smith are able to get a bunch of players to play to a system and to punch above their weight. I don't think that Smith is in the same category as the 4 managers I mentioned. I don't think CW is either but I think CW is probably top of the pile as the best manager from all the rest.
