Rodri better than Barry?! Behave.Rodri and Yaya are not comparable.
If Rodri is comparable to anyone in that team it would be Gareth Barry (who he is better than IMHO).
Yaya is more similar to KdB.
Silva could be Bernardo Silva or Foden.
You are probably right that Jesus will never score like Agüero, but remember WE STILL HAVE AGÜERO. When he leaves we need to buy a top class striker, possibly we could sign him pre-emptively but for the moment we still have Agüero and Jesus.
