Group E: FC Barcelona, Bayer 04 Leverkusen, A.S. Roma, FC BATE Borisov
The group, containing the title holders, will be an easy walk for them. Messi would be relishing his return to Bayer Leverkusen (which included a 5-goal salvo at the Camp Nou). Borisov should not be any competition to Barcelona whatsoever. A.S. Roma might be the only team that could get a point at the Stadio Olympico, but Barcelona have already beaten them in pre-season this year. It will see Enrique return back to Roma.
A.S. Roma should comfortably get second place given their squad additions and Leverkusen should take third.
