Certain about what regarding Maguire?Why are you so certain about the Maguire thing? I'm pretty sure we also saw reports of Phelan and Wells scouting Sancho, Bellingham and Bruno. Are two of those bad signings? Would Bellingham have been a bad signing?
Bellingham and Sancho were well known well before they were scouted by Simon Wells and Phelan. We tried signing Sancho when he was at City as a 17 year old. But my point is that if you want to have a solid mid to long term plan on the football side of the club, like we see at Liverpool, City, bayern etc. Then the mid to long term plan should be set by a figure head who utilises the scouting and data analytics departments at the club to the maximum. That's around 70 people who are working under that one figure head and hence will have a far more comprehensive outlook on how to develop the team in comparison to the manager model in the game today.
