not all teams are fighting for the title, there are many teams that even before starting series A already know that they are just fighting not to be relegated, teams like:
cremonese
fiorentina
verona
Lecce
bologna
Spezia
and so many others already know that they are not fighting for the title, they are just fighting not to be relegated or to end up in a good position
I know your assumptions are justified. Some teams are not fighting for the title but they are fighting to stay in the highest competition in Italy (Serie A).
About the title race, I have to agree about Milan, Juventus, Inter and Napoli. But for the last team, I think they have failed a lot of seasons despite having managed to end the season in second place several times.
For matchday 10, I don't think there are many interesting matches. Many favorites will probably win their respective match, so I think the multy bet on matchday 10 is great.
