A quickfire double from Roma kept things interesting
The first came from a fine finish after an aerial ball over the defence evaded the Liverpool players.
Edin Dzeko controlled it brilliantly on his chest to bring it down first time.
He then produced a clinical finish at the near post as Karius rushed out, slamming the ball into the back of the net.

The second goal came from the penalty spot after James Milner was adjudged to have got a hand on the ball.
Perotti stepped up and sent Karius the wrong way and all of a sudden Roma were back in the tie.
Liverpool now actually find themselves in a worse position than Barcelona were after the quarter-final first leg.
