i guess winners take all in the last matchday

Roma wins = u guys go through regardless what the other result in Germany
City wins = they go through but at the same time hoping CSKA wouldn't beaten Bayern

if both the matches Roma-City and Bayern-CSKA both ended in a draw then thing would get a little complicated

in the event of 2 draws, we only go thru if our result is scoreless, any draw other than that will make MC to have a better goal difference thus they will advance.

if we are serious about qualifying to the next round, we can't aim for a draw, we need to go all in for the kill.

AS Roma: Are guaranteed to qualify if they beat Man City on the final day, and would also qualify with a 0-0 draw if CSKA lose to Bayern. Roma will also qualify with any draw if CSKA draw too -- they took all of their points from CSKA and Man City, meaning they would win a head-to-head with the three sides on six points.
