That is a difficult question to answer and he may suffer for being associated to Mike Ashley.I know that I can possibly be accused of defending Arthur by saying this, but is that Charnley's responsibility as CEO or Mike Ashley's as the owner?
This is a good article if you have a spare 20 minutes on who exactly Charnley is. https://theathletic.com/2630880/202...acter-who-runs-mike-ashleys-newcastle-united/
My conclusion from that article and comments is that he is a yes man, promoted beyond his intelligence levels, but was set up to fail and is a decent bloke. Sounds like he would be a good club secretary/useful in carrying on in his advisory role for operations management.
I do hope we recruit a quality CEO though befit of our Premier League status and are not saddled with Ventros/Charnley.
