PARIS:  (DNA)  – Barcelona overcame the absence of an injured Lionel Messi to defeat Inter Milan 2-0 in the Champions League on Wednesday, while Borussia Dortmund signalled their intent with a 4-0 demolition of Atletico Madrid.

Mohamed Salah scored twice as Liverpool strolled past Red Star Belgrade, but Paris Saint-Germain needed a superb stoppage-time equaliser from Angel Di Maria to rescue a point at home to Napoli.

Barca collected a third win from three Group B outings as Rafinha, filling in for Messi after the Argentine star fractured his arm at the weekend, volleyed in the opener on 32 minutes at Camp Nou.

Philippe Coutinho rattled the crossbar in the second half before Jordi Alba sealed the points seven minutes from time to leave Barca on the brink of a spot in the last 16.

“We needed to step up given the absence of Leo,” Ernesto Valverde said. “It was in the head of us all.”

“We have a certain style, then Messi gives us a touch of brilliance that is extraordinary. When he is not there we have to supply it in some other way,” he added.

Bundesliga leaders Dortmund, who were missing in-form striker Paco Alcacer, delivered the performance of the evening as they handed last season´s Europa League winners Atletico their heaviest defeat under Diego Simeone.

Axel Witsel fired Dortmund ahead shortly before half-time at Signal Iduna Park, with substitute Raphael Guerreiro netting twice in the final quarter-hour either side of a goal by teenage England international Jadon Sancho.

Dortmund top Group A with a maximum nine points, although Atletico still remain favourites to progress alongside them after Thierry Henry´s Monaco and Club Brugge drew 1-1 in the other game.
