A Leeds source is claiming that Ken Bates is interested in buying into (or buying outright) Charlton. England's Mr Football certainly has an insatiable appetite for buying football clubs and turning them round whilst not leaving himself out of pocket (although it has to be said that the financial arrangements are not always transparent).
Leeds fans that I know were mostly glad to see the back of him, although it could be claimed that he steadied the ship after earlier errors. Mr Nice Guy he is not. I suppose one's reaction might depend on what kind of Charlton one wants: one with a serious chance of obtaining and maintaining Premiership status, or one that is very much in contact with its fans.
It may not be relevant, but Tony Jiminez had a spell running player recruitment at Newcastle United with Dennis Wise who is on good terms with Bates. Bates as chairman and Wise as manager is a distant prospect but one I would not welcome.
I cannot find any corroboration for this rumour, but I haven't dismissed it out of hand as it has a certain plausibility given that the club is in need of investment.
