One of the interesting things about the totally bullshit David Silva rumours is that it has prompted an awful lot of aggression and emotion. Many people see David Silva as something absolutely special, totally apart from anybody else in terms of his talent and have personally taken to him and his half-Spanish/half-Japanese attitude to things.
Sergio on the other hand is probably our most high profile player who created his own history with the Agueroooooo moment that constantly lives on even outside of City fans, to the point of people like Enes Unal mentioning it on Twitter years before signing. He is our talisman, his son Benjamin plays in our pre-Academy and despite knowing he could walk into Madrid or Barca tomorrow, he stays and vehemently tells the world that City is the place to be.
My difficult question is that if we absolutely HAD to move one of them on, which one would it be?
These rumours made me realise that if Aguero went to Real Madrid then I'd obviously be extremely disappointed but I could understand it in the grand scheme of things and would hope he goes over there and absolutely destroys the league. But if David Silva left then it would completely change my entire perception of the current squad - not in a rational way of course but Silva seems to be my impression of what an absolutely perfect footballer looks and plays like. His attitude is just tremendous and for my money he just seems to "fit" at City.
This isn't really a question about resale values, passing statistics or the like of, it's more asking that on an emotional level which one could you sacrifice to keep the other?
