That depends what you count as "top 4". The current top four ie Inter, Roma, Juve, Udinese or Inter, Roma, Juve, Milan as in the four strongest teams.
And do you compare that to Real, Barca, Espanyol, Atletico or Real, Barca, Valencia and Sevilla that are the four strongest sides in reality. Because if it's the latter Italy will have a hard task in such a comparison atm.
