Italian side Roma qualified second behind Real Madrid in Group G to reach the knockout stages, while Porto - who won the competition with Jose Mourinho back in 2004 - impressed with 16 points from a possible 18 to finish top of Group D.
Both teams would have been happy with this draw, which offers a fantastic chance to reach the last eight having missed potential ties against Europe's elite clubs.
Score prediction: AS Roma 2-1 FC Porto
Porto head into the first leg with the better group stage record, but Roma's run to last season's semi-finals should put them in good stead in terms of mentality.
Roma will expect to win the first leg in front of their own fans in the Italian capital, but Porto can and will threaten, so at least one away goal is likely.
