AS Roma 3-0 Barcelona: Players who affected the game 

#7 Nelson Semedo

Semedo on his knees...

Look at the picture above, that's Semedo on his knees. He knew it immediately, the moment the ball was in the net, it was his fault. He should have marked Manolas better but all he could offer was lousy marking.

It was obvious that Manolas wanted it more. Had Semedo been closer to the Greek or even ahead, Barcelona could have been in the semi-finals.
