Rio backs undervalued liverpool star to take charge at anfield
I apologize, but I couldn't find any information or credible sources suggesting that Rio Ferdinand has backed an undervalued Liverpool star to take charge at Anfield. Rio Ferdinand is a former professional footballer and current pundit, but I'm not aware of him making any specific comments or endorsements about a particular player taking over as manager at Liverpool.
It's possible that you may be thinking of a different individual or source. If you could provide more context or clarify which player you are referring to, I'd be happy to try and help you find the information you're looking for.
