As the dust settles on a Liverpool victory that will go down in the history books as one of the greatest Premier League matches ever we feel its important to wipe that dust away and look at the important factors of the game.
With nine goals to look at, as well as an angry German, this fixture had everything any neutral could wish for, a breathtaking performance from the Liverpool attack while the defence have some serious explaining to do.
A side battling for a Champions League place should be very worried if they are conceding four goals against a Norwich City side that look destined to fight off the threat of relegation season after season.
Regardless of injury problems, Liverpool possess the team to beat Norwich but have not being paying attention in defence class, as they looked far too happy focusing on outscoring their opponents rather than defending in a confusing but valiant style.
The goals scored and conceded: the good, the bad and the ugly
Nine is fine for the neutral fans but for the Reds it is a big red flag upon an already troubled season, after showing promise with a goal from Roberto Firmino in the opening 20 minutes, they failed to capitalise and left major gaps for the home side to exploit in a match where they should never have been troubled.
Fast forward three more goals and Liverpool sit in a very uncomfortable position at 3-1 down, the first Canaries goal highlighted how Liverpool have struggled defensively this season as they could not get the ball clear and allowed a free header to be cooly placed into the box which Dieumerci Mbokani Bezua exquisitely backheeled past Simon Mignolet.
Mamadou Sakho may be a solid defender but his backing off and failing to push his side out when the ball was clear was a rookie mistake and identifief how Jürgen Klopp's back four lack a real leader.
The second goal for the home side was one for Everton fans to cherish as new signing Steven Naismith fired home from an impressive angle which silenced the away support. Mignolet was beaten far too easily but the fact that there were already two players who allowed Naismith to wander unmarked in the penalty area even before the Scotsman's run is a major warning sign for the club.
Number three for Norwich was a penalty that should have effectively put the travelling side to bed. It began from a nothing angle and was a ridiculous foul to concede in the first place. Alberto Moreno was caught the wrong side of Naismith and dived in with almost impossible odds of winning the ball.
The Spaniard's defensive demonstrations over the past couple of seasons have been questionable to say the least but almost costing his side the match here should be worthy of a dropping to the bench.
It took 15 minutes into the second half for Liverpool to recover as Jordan Henderson led by example and struck past goalkeeper Declan Rudd to give his team hope of a recovery. With Firmino in top form, it didn't take long for the away side to get back level as in the 63rd minute the Brazillian was one-on-one with Rudd and gently looped it over the flapping 'keeper.
A clumsy backpass from Russell Martin was latched onto by James Milner who, with a slight shimmy, moved it past the Norwich 'keeper to tap home and give the Reds what looked like a beautiful ending to what began as a nightmare. Yet the trauma was still continusing on the field in stoppage-time.
After the announcement of five additional minutes, Klopp was raging and began to protest - which was made worse once the desperate Canaries launched a free-kick long upfield and again, following failure to clear, Sebastien Bassong fired home to send the German even more raging and the away players heartbroken - for all of three minutes.
With no time to spare Liverpool began to attack without remorse and after a cross from Emre Can was not cleared fully it allowed substitute Adam Lallana to volley home from inside the box in the last seconds of the game to take all three points back to Anfield.
Set-piece headaches
If you have ever wondered how to defend from set pieces - don't watch Liverpool's attempts. With free kicks and corner kicks becoming a real issue, they returned in this match to add even more to the dilemma.
Liverpol have conceded an embarrassing 32 goals from 23 games this Premier League season and with Stoke City, West Ham United and Leicester City all set to face the Reds in the coming weeks, Klopp must be feeling sick at the thought of organising his defence for set pieces.
With the German's side giving away on average just over 11 free kicks a game it does make you worry when a strong side make their way to Anfield, with Norwich scoring half of their goals from set pieces the current system is just not good enough.
The arrival of Steven Caulker, a powerful centre-back with Premier League experience may hold the key, but the Liverpool manager is reluctant to start the Englishman on-loan from Queens Park Rangers. A gamble on the 24-year-old could sure up the exposed defence that has already leaked in eight goals since December from Arsenal, West Ham and Watford.
Many critics looked to the last resort with Mignolet pin-pointed as a major influence on the opposition's advancements due to his timid character and often foolish errors, but with the Belgian goalkeeper recently signing a new deal at Anfield, clearly the manager refuses to blame the 27-year-old for any wrongdoing.
If Liverpool are serious about challenging for a place in the Champions League, Klopp should look to experiment with his defence in depth or run the risk of a season plagued by set piece casualties being classed as failure.
Alberto Moreno's defending sounding the alarms
A £12 million signing from Sevilla in 2014, Moreno looked to be the answer to Liverpool's left back situation for the next 10 years, yet he has struggled to show his ability defence wise while in attacking quality he has been one of the standout players.
With two defensive errors to his name currently, which both led to goals for the opposition, the Spaniard raises alarm bells often when he is caught out of position.
The 23-year-old demonstrated his strange defensive qualities when he audaciously opted to slide in on Naismith from behind before lunging at him a second time to essentially secure the penalty.
Moreno is a valuable asset to the Liverpool side and is clearly a favourite under Klopp as he has been a consistent face amongst his XI, but he has encountered very little in terms of a threat to his place as of recent.
With Moreno however, it may be his attacking elements that keep him in the side as he has already created 43 chances for his teammates - more than any other player for the Reds.
Liverpool are without any real strength in depth this season so this could potentially be why the former Sevilla player has featured so heavily with 30 appearances under his belt, so should Klopp be looking to purchase a more defence orientated left back or should he not give up on Moreno's unorthodox style of play?
Given that the only available left back is outcast Jose Enrique it seems likely that the youngster will keep his place unless a player who has just returned from injury recieves his long-awaited opportunity as Jon Flanagan who played left of defence during the Premier League title challenge in the 2013/14 season may be used in favour as the Scouser bids to earn a new contract at Anfield.
