It seems Silva's last 3 months have severely clouded judgments. But if I remember correctly, in the first half of the season Aguero, Negredo, Nasri, and Yaya were the only real contenders. Silva while technically supreme, was mostly second fiddle to Nasri's in carrying the creative load.
So how can that same Silva now be considered consistently good all year?
I really don't think it is close at all.
There is Yaya
Some gap
Then Fernandihno, Silva, Nasri and Aguero. The latter 2 fading due to injury, and Fernadihno became less influential in the last month as Silva influence peaked at Hull and Pool.
The Silva votes is simply a recency effect. Overall I think he ends up somewhere around Dihno and slightly above Aguero but far behind Yaya.
