[Trequartista]

For Serie A I would say:

Relegation battlers
Bologna
Cagliari
Chievo
Reggina
Catania
Lecce


Midtable
Siena
Torino
Atalanta
Palermo
Genoa


Euro Aspirants
Lazio
Napoli
Udinese
Sampdoria
Fiorentina

Then I would consider Roma, Inter, Milan, and Juventus as the "big four"



EDIT: La Liga:

Relegation battlers
Osasuna
Real Valladolid
Recreativo
Numancia
Sporting Gijon
Malaga


Midtable
Real Betis
Racing Santander
Athletic Bilbao
Mallorca
Almeria
Getafe
Espanyol
Deportivo

Euro Aspirants/Title contenders
Villarreal
Atletico Madrid
Sevilla
Valencia
Barcelona
Real Madrid

It's hard to separate the Euro aspirants from Real Madrid and Barca, because they seem like legitamate CL teams and possibly title contenders.
