PARIS — Barcelona overcame the absence of an injured Lionel Messi to defeat Inter Milan 2-0 in the Champions League on Wednesday, while Borussia Dortmund signaled 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.
