Late drama in UCL, as Liverpool suffer their first defeat of the campaign

Liverpool opened their Champions League title defense with a 2-0 loss at Napoli on Tuesday as Reds manager Jurgen Klopp questioned the decision to award a late penalty to the Serie A side.

Dries Mertens converted a penalty eight minutes from the end of an entertaining match after a contentious foul by Andy Robertson on Jose Callejon. Substitute Fernando Llorente then sealed it in stoppage time with his first goal for Napoli -- a measure of revenge after playing on the Tottenham side that lost last season's final to Liverpool.
