The Italians had it all to do tonight after managing only a goalless draw at home in the first leg.

But despite being under the cosh for much of the return fixture, Totti's 21st-minute header and Mancini's superb individual 43rd-minute effort saw them home.

Lyon, for whom Juninho was a constant danger, battled away gamely but they found visiting goalkeeper Alexander Doni in superb fettle.

He pulled off a string of fine saves, especially in the second half, to somehow keep the hosts scoreless in the tie.

In last night's other last 16 match, Valencia resisted a late surge from Inter Milan to hold firm and book their place in the quarter-finals on away goals.

A 0-0 draw at the Mestalla was enough for Enrique Quique Flores' men to go through thanks to the two goals they scored in Milan a fortnight ago.

But UEFA will be looking into a post-match fracas involving the two teams, which spilled over into the tunnel.
