The problem with this question is how are you defining winger? outright, touchline hugging wingers, wide midfielders, wing-forwards, inside-to-out-forwards and all the sub-categories fall under the same umbrella of 'wide-man' and all bring a different kind of intelligence to the role.
Do Cruyff and Rumenigge entire this discussion, for example? Boniek, Blohkin, Czibor, Overath, Nedved, Figo, Gento, Matthews all come to mind.
What I admire personally is the faster wingers who actually think on the hop. Slower ones don't have that choice; everything they do has to be considered because they didn't have the attributes to simply burn past or through opposition all game long, but those wide players that did, but still played within a team construct and made wise and considered choices more often than not, for me, that's something more special because they didn't have to - they could just mindlessly blaze through swathes of opposition and head down blast the ball or cross into an expected space and their job would still have merit and plaudits, so that's a more special mind, to me.
