#4 AS Roma

Wait, what?
For those of you who are still not over that shock, AS Roma did beat Barcelona in the quarters and will face off against Liverpool in the semifinals.
Unlike Liverpool though, AS Roma are in a serious fight for the fourth place with Inter Milan and Lazio (and maybe even Milan) but there is no way they will just ignore this competition after what they did in the quarters.
Roma have been doing pretty well against big teams so far - a 3-3 draw and a 3-0 win against Chelsea in the group stages are yet another example of this fact. They also beat Napoli recently 4-2 away from home and will be looking forward to the game against Liverpool.
No offense to Liverpool, but an attacking team like them was the best possible draw for Roma, and they will be generally happy with this fixture. They can sit back, let Liverpool tire themselves out and catch them on the counter.
While the chances of them making the finals are still bleak, anyone counting them out will have to do so at their own risk. There is no way they can overturn a 3 goal deficit, right?
