I choose to differentiate between wide midfielders, like Camo or Ribery, who start wide, but want to come inside and link up and pure wingers, like Robben, who just look to beat their man out wide and put a cross in.
Not really.
Camo comes wandering inside a lot and contributes to the play in the centre.
Someone like Robben, or a young Ryan Giggs, is a true winger in my book.
