NAPLES – Juergen Klopp was frustrated by Liverpool’s poor finishing after his side began their Champions League title defence with a 2-0 defeat away to Napoli, who scored two late goals at the Stadio San Paolo on Tuesday.
Dries Mertens scored from the penalty spot with eight minutes remaining after Andy Robertson tripped Jose Callejon inside the box and Napoli substitute Fernando Llorente added a second in stoppage time to put the result beyond doubt.
Klopp’s side became the first competition winners to lose the opening game of their Champions League defence since AC Milan were defeated by Ajax Amsterdam in 1994 and the German was concerned by his players' wastefulness.
“It should hurt because there were opportunities for us,” he told BT Sport.
“It was an open game with a lot of counter attacks, but we didn't finish them off and that is a problem. In the second half it was a wild game, they were running and we were running.”
