Liverpool and Manchester United had to settle for a point after a goalless draw at Anfield.
Billed as one of the biggest games of the Premier League season so far, neither side was able to break the deadlock.
The home side, missing the injured Sadio Mane, had the better of the chances but were unable to find a way past David de Gea in the United goal.
Jurgen Klopp threw on Alex Oxlade-Chamberlain, Daniel Sturridge and Dominic Solanke but it proved to be in vain.
At the other end, Romelu Lukaku endured a frustrating afternoon in front of goal.
Here, we rate the players on both sides...
Liverpool
Mignolet 7
Important save just before the interval, had so little to do for so much of game
Gomez 6
Gave everything in trying to overlap and create space, strong in defence too
Matip 7
So very nearly proved Reds hero, but denied by De Gea, looked composed on ball
Lovren 6
Given tough time by Lukaku's bulk, but kept at it, even though looked troubled
Moreno 6
Bit of an enigma. Capable of good things, but loses concentration too easily
Wijnaldum 7
Started on fire, and looked like could be difference, but faded as game dulled
Henderson 7
Kept his side at it and working forward, and big role in making this team tick
Can 7
One half chance just after break, looked good in getting forward, stepped up
Salah 8
Most dangerous player and rammed Chelsea experience down Mourinho throat. MOM
Firmino 6
Always looked just about to catch fire, never quite did, but still showed moments
Coutinho 6
Has to go a little too deep in games like this, and that raises a few questions
Subs:
Oxlade-Chamberlain 6 (Salah, 78)
Sturridge 6 (Coutinho, 78)
Solanke 6 (Firmino, 88)
Manchester United
De Gea 7
Fine save from Matip in first half to prove he's best in League...United's best ever keeper?
Valencia 6
Like many United players, seems to have bulked up massively under Mourinho. Solid unit
Smalling 7
Booked. Apparently manager not his biggest fan, but ability to come into huge game calmly is key
Jones 8
Outstanding. Used his size and (new found) strength to hold Liverpool at arms length
Darmian 6
Mourinho shut up shop and that saw full backs sit incredibly deep – played that role well
Young 6
Hard work down the flank, mostly running back, which was precisely why he was selected
Hererra 6
Fouled for fun because was allowed to get away with it, and did his job to perfection
Matic 6
Had one job to do, and did it with his usual impeccable precision. Defend, defend, defend.
Martial 6
Looked distinctly unhappy being asked to play virtually as a wing back, but worked very hard
Mkhitaryan 6
Touches of class around the box, played behind the striker and lurked with menace
Lukaku 6
Spent most of the game seething at the lack of service, but caused problems without it
Subs :
Lingard 6 (Mkhitaryan 63)
Rashford 6 (Martial 65)
Lindelof 6 (Young 90)
Ref : Martin Atkinson 6
