18) Atalanta
19) Cagliari
20) Lecce
Juve is still Juve and altough there were no big signings there are some positive things like:
1) I don`t expect too much refereeing errors like last year
2) I expect us to perform like the 2nd half of the last season rather than the 1st one
3) Juve didn`t sign anyone extaordinary but Poulsen is quite good and altough he didn`t cost us any money don`t forget Giovinco!
Marchisio could also be a surprise
If we would have signed someone good for the defence and someone who could create as well as give us defensive strength I would have said that I don`t see Inter as favourites anymore but we have Secco and it didn`t happen so... :\
About Roma they are a good team and a 3rd place is surely a place Roma could finish in
Milan- They are a good team with the best potential in Italy but something always lack there and I just can`t see it change
Ronaldinho would perform good but not like his Barca days Shevchenko would be better than his Chelsea days but still not as good as his former Milan days
Fiorentina- I have to say I don`t understand where all this hype comes from they are not that good!!!
Juve Milan and Roma are far superior even though with Milan you never know which Milan it is going to be the good one or the medicore one
