Liverpool vs Arsenal was always going to provide fireworks after their first meeting this season.
The two teams served up a truly entertaining clash at the Emirates Stadium, with goals from James Milner and Alexandre Lacazette featuring in a closely fought 1-1 draw.
And their latest clash started in a similar vein with no less than three goals gracing the opening 15 minutes on Merseyside.
Arsenal surprisingly took the lead at Anfield and from an unlikely source, with Ainsley Maitland-Niles tapping home at the back post from Alex Iwobi's cross.
However, the lead didn't last for long with some questionable Arsenal defending allowing Liverpool to work their way back into the game.

A series of deflections in the penalty area, sparking by a botched clearance, allowing Roberto Firmino to find the net in front of an open goal.
And just a matter of seconds later, he produced a superb individual goal, slaloming past two Arsenal players and slotting the ball past Bernd Leno.
Entertaining stuff but the first-half wasn't without its controversy.
That's because Sadio Mane was caught producing some bizarre behaviour in the seventh minute and it sparked a series of angry posts across Twitter.
The Liverpool forward was seen grabbing Stephan Lichtseiner by the neck off the ball, seemingly losing his head in a brief moment of anger.
Although suggestions that Mane 'strangled' him are probably taking things too far, plenty of supporters want him banned for the incident.
Check out images of the clash below and fan reaction:

It's poor from Mane, there's no doubt about it and plenty of Liverpool fans are already worried about the possibility of a retrospective ban.
There was no card for Mane at the time and the BT Sport commentators seemed to miss it, but the large reaction will only spark further debate.
It certainly wouldn't be the first time that the Premier League dished out a ban for an off-the-ball incident and thankfully, it wasn't as bad as it could have been.
