In disarray for 45 minutes and behind to a rare headed goal by Philippe Coutinho, Arsenal were in danger of suffering a pre-Christmas nightmare on Saturday (NZ time) when Mohamed Salah raced away to put a rampant Liverpool 2-0 ahead in the 52nd minute with his 15th league goal of the season.
But the hosts suddenly came alive and, unbelievably, they were ahead by the 58th minute with goals from Alexis Sanchez, Granit Xhaka and Mesut Ozil turning the game upside down.
