3. Mateo Kovacic
If City want to get a player who can get better each season, they should attempt to sign Kovacic. The Inter Milan player is highly rated, even the legend Javier Zanetti considers the Croatian to be one of the best prospects to come out from Europe since a certain Cristiano Ronaldo. Adept at playing as the attacking midfielder, Kovacic could bring back the bite that has been missing from the City midfield for quite some time.
