Barcelona set up a mouth-watering Champions League quarter-final clash with Bayern Munich after beating Napoli 3-1 to progress 4-2 on aggregate
 After surrendering rather meekly to Real Madrid in the La Liga title race, the Champions League is Barcelona's only hope of a trophy this season and Clement Lenglet got them off to the perfect start by heading home a Ivan Rakitic corner (10)
Lionel Messi then came to the party with a sumptuous effort (23) and had one chalked off harshly by VAR for handball
The Argentine then won a penalty for his side, aided by VAR which led the referee to take a second look at the incident on the touchline monitor
 Luis Suarez knocked home the penalty (45+1) before Lorenzo Insigne capped off an intense first 45 minutes by scoring from the spot himself (45+5)
Napoli needed to score twice to keep their Champions League dream alive but despite showing plenty of endeavour and having a goal ruled out for offside by Arkadiusz Milik, the Italians could not find a way past a hard-working Barcelona side
Barca will play Bayern at the Estadio da Luz on Friday, August 14 in a one-legged shootout to reach the semi-finals
It had been almost half a year since these two played out an edgy 1-1 draw in the first leg in Naples, which left this clash delicately poised
 Since then, Barcelona had surrendered the La Liga title to Real Madrid and Napoli stuttered to a seventh-placed finish in Serie A
Barcelona started without much zip and rhythm in an eerily empty Nou Camp and Napoli produced the early front-foot football
 A lazy defensive clearance from Gerard Pique dropped to Dries Mertens inside 90 seconds but his effort wasn't clearly struck from 12 yards out and looped back off the outside of the post with Marc-Andre Ter Stegen merely a spectator
Napoli were left to rue that opportunity as Barcelona grabbed the all-important opener on 10 minutes
 The Napoli defence will still be wondering how Lenglet became free from eight yards out following a Rakitic corner
 He didn't waste the opportunity, powering a header into the far corner with Napoli appealing for a foul on Kalidou Koulibaly that wasn't there
The goal settled Barcelona into their stride as Messi took centre stage
 There looked little danger when he picked up the ball on the corner of the penalty area surrounded by four Napoli players, but he managed to wriggle his way into the area
 And despite losing his footing, he managed to regain his composure to curl a majestic finish into the far corner
Napoli were now just spectators in the Messi show as he thumped home from close range following a superb Frenkie De Jong cross
 However, VAR - after three minutes of deliberation - decided that the ball brushed off Messi's arm before he stroked home and ruled out the goal
The score remained 2-0 but only for a few minutes with Messi once again playing a huge role in Barca's third goal
Koulibaly was caught napping by Messi inside his own box and cleared out the forward by kicking through his lower leg
 Initially, the referee waved played on but VAR stepped in to advise the referee to head over to the pitch side monitor to review the decision
 The replays clearly showed the foul by Koulibaly and Suarez, with Messi receiving treatment, smashed home the penalty
The three-goal cushion only lasted three minutes though with Napoli keeping themselves within touching distance by winning a penalty right on the stroke of half-time
 Mertens was clipped by Rakitic inside the box and Insigne found the bottom corner from the spot
Napoli required a two-goal salvo and gave the steep challenge a good go in a second-half showing that would have pleased manager Gennaro Gattuso
Hirving Lozano headed over from 12 yards with his first touch off the bench before fellow substitute Krystian Milik did find the net from a similar position but his celebrations were cut short by an offside flag that spotted his was half a yard offside
It was a case of job done for Barcelona but a tougher test awaits next Friday
Who else? We've come to a stage in Messi's Barcelona career where he is truly indispensable to this side
 Before, there has been a Xavi or an Andres Iniesta to shoulder the burden but Messi is a one-man band these days
 It's almost like he's wearing an Argentina shirt such is the pressure on his shoulders to be the man to make a difference
 Without him, Barcelona wouldn't have won this match
Staggeringly, Barcelona had just seven shots on goal in this encounter with Messi's influence in the final third absolutely massive
 He made something out of nothing to double the lead for his side with a classic Messi finish before his tenacity won the penalty for the all-but match ending third goal
The timing for Koulibaly to have a howler couldn't have come at a worse time or on a worse stage
 The defender is one of the hottest properties in Europe, with his commanding performances over the past few seasons in Naples seeing him linked with Manchester City, Manchester United and Paris Saint-Germain
Napoli president Aurelio De Laurentiis has said the club would laugh off any offer below £60m and, instead, value him at around £90m
 Well, on this performance no elite side is going to fork out that sort of money in this current financial climate
 He rarely looked comfortable in possession throughout, summed up by an inexplicable 50-yard pass that went so wide of its target it went out for the corner that led to the opening Barcelona goal
It was Koulibaly that was supposed to be marking Lenglet from that set piece, too
 As the Barcelona man headed home the Napoli defender was on the floor having been blocked off by Suarez too easily
 Things were about to get worse
His dallying on the ball allowed Messi to nip in and his clumsy challenge through the back of him allowed Barcelona to extend their lead from the spot
 A night to forget for the 29-year-old
