Man Utd for the right reasons, because they are pretty much underperforming in the EPL.

Man City entah I dont know how. tactical error against European teams. considering its their first time in CL.

as for Inter Milan, now that one amazing story. not even top 10 and manage to qualify. don't see them going through the Knockout stages even (unless Ranieri becomes the tinkerman again)

Arsenal manages to pick up their form at the best time of the season, justified why they can qualify (apart from the bashing in their last match)
