Napoli heaped yet more misery on Rangers' luckless European campaign on Wednesday night, as Giovanni Simeone's double and a late Leo Ostigard header secured a convincing 3-0 victory in the Stadio Diego Armando Maradona
Napoli boss Luciano Spalletti was adamant there was no chance of his side underestimating Rangers pre-match, in spite of a 7-1 defeat by Liverpool in their last group outing, but their ruthless performance told a different story
"You can't imagine the opponents we are facing," opposite number Giovanni van Bronckhorst concluded as his side were taken to task by the Italian outfit
 "The level is immense
"Napoli, top of Serie A and leaders of Group A, demonstrated exactly why they are dominating on both domestic and European fronts with a display that blew the winless Scots away within 16 first-half minutes
Simeone's quick-fire double had Napoli cruising, before Ostigard powered a header beyond a helpless Allan McGregor from a pinpoint Giacomo Raspadori corner late on
With a perfect set of results, ahead of a showdown with Liverpool next week, Napoli have become the first Italian side to win their opening five games of a Champions League campaign since Juventus achieved the same feat in 2004-05
 They've also set a new club record of 12 consecutive wins in all competitions
The Gers, contrastingly, have lost all five of their Group A games, conceding 19 in the process
 They still have a slim chance of claiming a Europa League spot, at the expense of Ajax, but would need to better the 4-0 scoreline from their reverse fixture with the Dutch when the two sides meet in Glasgow on November 1
Last season's Europa League finalists will be out of Europe altogether barring an improbable thrashing of Ajax in their concluding game at Ibrox in six days' time
Napoli, unbeaten in 16 games this season, were devastatingly fast out of the blocks, scoring twice in the opening 16 minutes
There was just 11 minutes on the clock when Giovanni Di Lorenzo sent the impressive Simeone scurrying down the right flank to score a clinical opener, arrowing a precise shot past McGregor and in at the far post
Simeone then headed home a teasing cross from Mario Rui four minutes later, with defenders Leon King and Ben Davies powerless either side
The visitors rallied in the second period, restoring some beleaguered pride, and nearly reduced arrears when Ridvan Yilmaz presented Alfredo Morelos with a back post tap in, only for the Columbian to completely miscue his attempted finish
Defender Ostigard added the gloss to an effortless home win in the 80th minute, rising to power Raspadori's corner beyond McGregor to round off an impressive Champions League debut
"We should see the performance today in terms of the Champions League
 For me, it was a positive one
 If you compare it to all of the games we've played
"We have some good moments in the game
 Too many games we've conceded too many goals easily
 The biggest example is against Liverpool at home
"You can't imagine the opponents we are facing in this moment in this group
 We are thinking about our performances of course, but we have to be realistic
"That's always the case when you play in the Champions League
 The level we are facing at the moment in this group is immense
 If you look at the results elsewhere, big teams, Barcelona and Juventus, don't even qualify
"So, that's all I can say
 It's the level we face
 You have to be ready for 90 minutes
""We are disappointed to lose the game
 I felt we can take some positives from that compared to the other games we have played in the group
"We let two easy goals in in the first half and I felt we had two good, big chances that could have levelled the game
"We have to take the positives from the game and build on that
 They took their chances but that is the level we are playing at and we have to learn from that
