I'm not suggesting the bloke you're referring to is comparable Keith, but Ricky Lambert drifted around the lower-leagues scoring goals until Southampton (I think?) took a punt on him, despite earlier being regarded as too one-paced to make the step-up. He ended up winning full England caps IIRC?
Aye, and whatever happened to that lad who used to play for Fleetwood Town, summats Vardy?
