Elsewhere, last season's beaten finalists Arsenal eased to victory over Lille while Barcelona came from behind to beat Galatasaray but Inter Milan lost a seven-goal thriller at home to Club Brugge.

Atletico, who lost at Liverpool in their opening European encounter, took the lead inside the opening minute in the Spanish capital through Pablo Barrios. Alejandro Grimaldo struck the woodwork from a free-kick later in the first half.
