​SSC Napoli fans sang along the ​UEFA Champions League theme song that was played ahead of their team's clash against FC Barcelona and the whole scenario around the stadium would give you goosebumps.


Napoli and Barcelona ​drew 1-1 in their ​first leg last 16 Champions League tussle at Stadio San Paolo on Tuesday evening, with Dries Mertens' goal making him the Italian side's joint-leading goalscorer in their history.

Fans on Twitter had a lot to say regarding this amazing atmosphere created by Napoli fans:










Dries Mertens gave Gennaro Gattuso's side a shock lead in the first half after bending in a lovely effort past Marc-Andre ter Stegen.


Quique Setien's side responded in the second half and were back level before the hour mark. Nelson Semedo whipped a ball in for Antoine Griezmann to lash home and bring the sides level.


Callejon was set through on goal moments later, but he wasted the chance to restore his side's lead. Despite both sides best efforts, there wasn't to be a winner for either side, but Arturo Vidal was sent off in the final minutes for two bookable offences.
