Another weakness is the lack of a medium - long term vision. The way City prepared for Pep. The way Liverpool are set-up. Having everything in line regarding managers, scouts, coaches, DoF etc.
Woodward has gone from Van Gaal, a possession manager to Mourinho, a manager who doesn't want possession, to Solskjaer, who wants to bring in people who understand the club and young british talent. Each manager wanted their own type of player and we're left with a a blend of players bought by 3 very different managers.
Can you imagine City appointing someone like Simeone or Allegri when Pep leaves? And suddenly having to shift Pep types like Ederson, Laporte and Rodri so that Simeone can have his type of player instead. No chance. They will appoint a manager with similar ideas. Liverpool will replace Klopp with someone similar. No doubt these clubs already have some kind of plan in place, ready for this. Who cares about any other club right now, these 2 are our biggest rivals and the ones to catch. We need to be run as good as them or better.
I will bet Woodward and Co. have no idea what our manager and squad will look like this time next year, let alone the next 3-5 years.
