We paid the same or slghtly more for Milner as we paid for Silva, Yaya Toure & Tevez. He hasn't given us a quarter of what any of those have given us.
He's too slow to be a winger, doesn't run games, doesn't score goals, doesn't have the power of Yaya and doesn't have the creativity of Silva. He'll work his socks off but that's not enough in itself.
