Holders Liverpool began their defense of the Champions League trophy with a defeat against Napoli on Tuesday (Sep 17).
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.
