Ramsgate resident and Voice of the Valley editor Rick Everitt provides a typically trenchant and well-written analysis of the managerial changes at Charlton: Disgusted of Ramsgate
I think he is a bit hard on Katrien whose programme article was written before events unfolded, but I would agree that the fundamental problem has not been poor coaching or tactics but the thinness of the squad.
I don't think clubs benefit from being on a managerial merry go round, even if all the managers share the same nationality. However, there are a number of Charlton owners and managers I have had issues with in the past, not least the Glikstens. I hope that Luzon is a pleasant surprise (as Riga was). But he will need some financial backing if he is going to succeed.
For now he is the Charlton manager and, as such, has my backing and good wishes. I support the club which transcends any particular individual, whether owner or employee.
