Just wondering if the op has played football at any decent level? Highest I got was the lancs and Cheshire league which is fuck knows how many levels down the pyramid, but it's a fucking lot!!!
Anyway, about 4 years ago we had Gareth Whalley (played for crewe then Bradford in the prem) play for us in a title decider. He came on as a sub and his talent shone like you can't believe, and he was 37 then. To even play for teams in the northern premier you have to be a hell of a player, never mind the premier league.
So, not one single player in the any of the top four divisions, and probably a good few leagues below, can blag it. It just isn't possible!!! You have to have considerable talent or you'd be found out immediately.
As an aside to the above point, in the changing rooms after the afore mentioned game (which we won, beating Whalley range) I asked Gaz Whalley who the best player he ever played against was. He thought for a second before replying, "Patrick Veirra at Highbury was pretty good". How fucking awesome it must be to be able to say that sentence.
