Well, that wasn't supposed to happen, was it?
Liverpool, the Champions League holders, faced an admittedly tough opening challenge in their bid to defend their crown, travelling to Stadio San Paolo to face last season's Serie A runners-up Napoli on Tuesday.
The game was a close run thing, with both Alex Meret and Adrian pulling off top saves at various points, but Napoli would eventually pull clear thanks to Dries Mertens' penalty - scored after Andy Robertson was adjudged to have brought down Jose Callejon - and substitute Fernando Llorente's prodded finish following Virgil van Dijk's sloppy pass.
