my predictions are:
1.napoli
2.arsenal
3.borussia dmd
4.marseille
reasons why i say this:
?NAPOLI went out this transfer window
and bought an abundance of talent. These
signings include Higuain,
Callej?n,Albiol,Mertens and

Zapata also have a champions league expirienced coach in Rafa Benitez
?ARSENAL is a compact team plus the addition of ozil to the team is great for them and has an expirience coach you cant see them not making out of the group
?DORMUND i feel is overated i dont see it the fast tempo it used to play with plus they have lost a valuable playet in gotze
?MARSEILLE....well a good team but just happen to be in the wrong group at the wrong time/Form
