I haven't got a fucking clue, but then I'm not the owner of a multimillion pound business that spends hundreds of thousands of pounds on a professional global scouting network, and part owner of the world's foremost football agency.
Me not being able/arsed to name a bunch of footballers capable of being a genuine first team option as a wide/inside forward, or as a partner to Raul, or if desperate as a lone front man, doesn't mean they don't exist. We managed to sign one for £15m in the championship, after all.
That we didn't sign one to replace the one that left is either a management failure, or a scouting failure.
Or it's the fault of del woppio off the Internet.
