Despite being a man up after Marco Materazzi was sent off in the 30th minute, the Reds didn't break through until the last five minutes when late goals from Dirk KuytandSteven Gerrardgave Liverpool the victory.
"I had confidence we would score because the team was playing well," Liverpool manager Rafael Benitez said. "We kept trying to pass the ball and create chances. We knew it could happen and scoring two goals at the end is much better."
The win came three days after Liverpool fell at home to second division Barnsley in the FA Cup.
Roma ended a string of three straight losses to Real Madrid at home when it beat the Merengues, 2-1. Roma captainFrancesco Totti'sresourcefulness was critical to the Italian club's comeback after Gutiput Real Madrid ahead in the 8th minute. Totti set up Brazilian Mancini, who fed David Pizarro for the first goal, and assisted on Mancini's winning goal.
In other matches, Germany's Schalke beat Porto, 1-0, on Kevin Kuranyi's early goal, while Chelsea earned a 0-0 tie at Greek champions Olympiakos.
