Just take a look at the potential pots for the groups Fred.
Milan are group holders and with a little luck they can get teams like Spartak, Zenit etc in the second round.
Of course, they can get a group with Real and Tottenham and they could even be eliminated in the groups, but there are many teams missing in CL this year (Porto, Juve, Liverpool) which automatically makes the groups weaker.
In pot 2 (as things stand right now. Some of these still need to qualify) there are Lyon, Real, Werder, Roma, Shakhtar, Benfica, Valencia and Marseille. In pot 3: Zenit, Panathinaikos, Tottenham, Rangers, Ajax, Schalke, Basel and Anderlecht.
With the exception of Real, none of the others are too scary and if Milan don't get Real in the groups, then they might win the group and get an easy opponent in the 1st knock-out round. If Milan don't win their group then they will probably be eliminated in the next round.
