Benjy Nurick has written his latest analysis of Charlton's problems and it is certainly a comprehensive treatment: https://londonnewsonline.co.uk/charlton-athletics-performances-have-collapsed-as-thomas-sandgaard-faces-first-big-call-as-owner/?fbclid=IwAR3-9FnKVUcz3pvmbRbQ-u7MAqG8CIv5G4ask2IOS9MzGBANtuM_q1MWMuE
Nurick puts the arguments for and against retaining Bowyer. Essentially what he says if that we think Bowyer is the person to rebuild the makeshift squad in the summer, he should stay. If not, he might as well go now.
Owners need to be ruthless, but it is easy to get into a destructive cycle of sacking manager after manager in a search for 'the one'.
At the end of the day he doesn't give an opinion and says it is up to us as fans. We are often told that football is all about 'opinions' and that is certainly the case at Charlton.
I am happy to leave it to Sandgaard. It's his money and he has extensive experience as a successful businessman. Of course, football is a very odd kind of business as many owners have discovered.
