group f

group h
AC Milan
Lille

for the offs i think my knowledge serves me right in thinking that you cant play someone from your own country, and ofc 1st must play a 2nd place so i think the following can happen.

chelsea vs inter milan / psv / roma / real madrid / celtic / porto / lille
arsenal vs inter milan / psv / roma / real madrid / celtic / porto / lille / barcelona
celtic vs chelsea / bayern munich / liverpool / valencia / lyon / arsenal / ac milan
man u vs inter milan / psv / roma / real madrid / porto / lille / barcelona
liverpool vs inter milan / psv / roma / real madrid / celtic / porto / lille / barcelona

since all 4/4 of the english teams topped there group there ofc have the easiest chances to proceed, and all have the same pool of teams to play against. Celtic are in trouble i think :D
