My friend are you serious?
1) Fernandinho may not be a better dribbler, but he has the willingness to get forward and he can place the ball in the net. Paulinho has managed to score a few tap-ins, but he's scored less than he's capitalized on easy goal-scoring opportunities. The key difference though, is that Fernandinho uses the space ahead of him instead of always looking wide, which is exactly what our current midfielders you propose incessantly do.
2) Most importantly, you're saying a central midfield including Silva and Nasri is the same as having one of Paulinho, Sandro, Capoue, Dembele, and/or Bentaleb? That is the same as saying 2=3. Those two players play centrally, but you're talking about pushing Eriksen, Holtby, and/or Lamela up and out on a forward line. Quite frankly mate, that makes the antithesis of sense.
Not sure you have read what I have said, Man City play two central midfielder and two false wide players in Nasri and Silva then two strikers up top sometimes, I am not talking about playing Eriksen as a forward, I am talking about using Eriksen and Lamela like Silva and Nasri not as Dezko or Aguero . I am talking about playing a system similar to Man City, this is not to say we will be as good but it is a good alternative to having wingers which have not worked for us recently and as Man City proved its not the antithesis of sense. Man City don't really have wingers when not using Navas and don't see why we could not.
