That's how I see it. Besides, 10 years ago guys like Messi, Ronaldo, Dinho were practically non-existant. Their positions, which you call wingers, I call forwards, came with the popularity of the 4-3-3, left footed players attacking from the right, etc. They're basically never in the defensive side of the game, something which wingers generaly do.
If we're gonna put Bale and Ronaldo in the same bracket, we might as well put Pirlo and Zidane in the same bracket. What, they're both playmakers and play in the middle. Yeah they play from the wing, but are completely different types of players.
