Benfica and Porto were possibly the only potentially "easy" Pot 1 teams we could have faced. So we had a 66.33% chance of drawing a tough one. It would have helped had Arsenal gone out last night. Although I'd like them tied up in Europe as long as possible from the PL perspective.
Among the Pot 3 teams several tougher than CSKA.
So really the only bad luck I see is drawing Roma who were easily the best team in Pot 4.
That being said we are more than capable of beating CSKA home and away, And I reckon we can draw with Roma away. Job done.
Unfortunately with Liverpool, Chelsea and Arsenal going through it will be 50/50 meeting someone like Barca, RM, AM, Juventus, Dortmund, PSG.
