Liverpool were held to a stalemate 0-0 draw against Manchester United on Monday in what was a forgettable affair on Merseyside.
What many expected to be one of the most exciting fixtures of the Premier League season so far, instead turned out to be somewhat of a bore-fest with neither side offering any real threat to the opposition goal.
The first 45 minutes were mundane as both sides high pressure allowed neither chance to attack and find options through the middle of the park.
And while things did improve in the second half - with both Philippe Countinho and Roberto Firmino being denied by an excellent save from David De Gea and last ditch tackle from Antonio Valencia respectively - it certainly wasn't a great spectacle.
A point will be enough for both sides to stay in contention for a top four challenge come the end of the season, however the home side will be upset they could not snatch all three points, especially considering their dominance late into the second half.
Here are five things we learnt from tonight's game at Anfield...
Keeper Troubles Continue
Simon Mignolet's replacement and summer signing Loris Karius had a shaky game throughout, and often looked uncomfortable in possession. While United's high pressing certainly didn't help, his insistence on playing it out from the back instead of sometimes just clearing his lines made his life more difficult than it should have been.
It is early days in his Anfield career and he certainly will need time to adjust, but the German needs to be more assured with his distribution if he is to force Mignolet out of the side on a permanent base.
Adam is the Key
Liverpool looked instantly more dangerous once Adam Lallana entered the field to replace Daniel Sturridge with 60 minutes gone, and not only because Sturridge did next to nothing for his hour on the pitch.
The Englishman's ability to twist and turn in the midfield as well as out wide caused trouble for United and he provided a different outlet when going forward, often making runs out wide or in behind. His midfield counterparts Emre Can and Jordan Henderson don't have that in their locker and hence Lallana brings a balance to the Reds midfield they lack without him.
Pressing Matters
All the hype going into the game was about Liverpool's 'pressing' style of play which makes life difficult for their opponents on the ball and has been a major part of their success so far this season.
But it was in fact United who seemed to play Liverpool at their own game.
Whether it was a stroke of managerial genius from Mourinho or not, his side were relentless in closing down. Mourinho's tactics were spot on to pick up a draw, as he often plays for in challenging away games, and Liverpool struggled to create many meaningful chances.
United's Cutting Edge
Too often Manchester United this season have relied on their wonderkid Marcus Rashford to save the day, however they must learn they cannot always do so.
Rashford had little luck going forward this evening and instead spent most of his time tracking back down the flank, much to his credit it must be said.
United's front line looked unbelievably lacklustre and Zlatan Ibrahimovic did little to trouble anyone all night, nor did (unsurprisingly) Ashley Young. Anthony Martial, Jesse Lingard and Henrikh Mkhitaryan are clearly being sorely missed as the Red Devil's lack a cutting edge with only the Swede up top and Rashford out wide.
The class of the in-form Juan Mata was sorely missed, too.
Poor Paul
It was yet another disappointing display from Paul Pogba, many of whom expected to rise to the big occasion, especially considering his wonderful performance whilst on international duty for France last week.
It was not to be however, and the clubs record signing once again looked out of sorts, instead being eclipsed by the impressive Ander Herrera.
Albeit he may not have the players around him to be performing to his absolute best, it is still clear for all that the former Juve man needs time to become accustomed to the Premier League, Mourinho's style of play and indeed his United team-mates.
