Paris: Holders Liverpool began their defence of the Champions League trophy with a defeat against Napoli on Tuesday, while one missed spot-kick condemned Chelsea to defeat against Valencia and another came to Barcelona’s rescue.
Liverpool survived a 1-0 defeat in Naples in the group stage last season to go on and win their sixth European Cup, and this time a 2-0 reverse at the San Paolo made them the first reigning champions to lose their opening game in the competition since 1994.
Both sides had chances in the Group ‘E’ clash before the hosts won a late penalty with barely 10 minutes remaining when Jose Callejon went down under an Andy Robertson challenge.
Dries Mertens beat Adrian from 12 yards and substitute Fernando Llorente — who played for Tottenham Hotspur against Liverpool in last season’s final — then took advantage of a rare defensive lapse by Virgil van Dijk to make it 2-0 in stoppage time.
Liverpool must now bounce back in two weeks when they host Austrian champions Salzburg, who made a stunning return to the group stage as teenage forward Erling Braut Haaland netted a hat-trick in a 6-2 demolition of Genk.
Salzburg had fallen in the qualifying rounds in the last seven campaigns but finally progressed this season to the group stage for the first time since 1994-95.
Haaland, the teenage English-born Norwegian striker whose father Alf-Inge played for Manchester City, gave Salzburg a second-minute lead and netted twice more before half-time.
Aged just 19 years and 58 days, Haaland is the third-youngest player to score a Champions League hat-trick behind Wayne Rooney and Raul, according to sports statisticians Opta.
