There seems to be some deliberate double-dealing going or some fans are unable to distinguish between past and present.
The real ronaldo morphed into fat ronaldo. The very greatest of players are the greatest players for a limited period of time. And in Yaya's case he was a physical phenomenen. A man mountain who if you could keep up with him was untackleable. But the mountain requires a powerful engine.
The current Toure is not producing this season. At the best he is flickering and despite what you claim we haven't tried to play without him. He has played 26 league games. City have played 30 league games.
I refuse to believe that Pellegrini could not field a competent City midfield from the likes of Fernandinho, Fernando, De Bruyne, Nasri, Delph, Navas and Silva.
For a period this season we had little alternative but to play him. Now as injured players return we have alternatives. They are not as good as Yaya of old. Very very few are, but it's the manager's job to get the best out of his current squad and our midfield players are better than the current Yaya plus 3/4.
