Roberto Firmino's powerful finish earned Liverpool a draw in an incredible Premier League encounter that had seen Arsenal score three goals in just five second-half minutes.
The Gunners, during Friday's clash, had been trailing 2-0 after Philippe Coutinho scored his first headed league goal in England before Mohamed Salah added a second early in the second half with a deflected strike, according to a BBC report.
But Arsenal suddenly came alive as Alexis Sanchez headed in Hector Bellerin's cross from close range before Granit Xhaka's thumping strike was too powerful for Simon Mignolet's weak save.
Barely two minutes later Mesut Ozil put Arsenal ahead with a neat clip over Mignolet.
Play swung from one end of the pitch to the other at blistering pace, with both sides looking capable of scoring with every attack.
But it was Liverpool who had the final say in one of the most thrilling Premier League encounters in years as Petr Cech could only take the sting out of Firmino's shot and the ball bounced over the line.
The point meant Liverpool held onto fourth place, with Arsenal remaining fifth - a point behind the Reds.
