Arsenal produced a stunning fightback on Friday night after a woeful first-half display to overturn a two-goal deficit against Liverpool.
But they were denied an improbable victory as Roberto Firmino salvaged a 3-3 draw for the visitors at the Emirates.
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.
That was 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.
Firmino made sure Liverpool returned north with a point with a 71st minute equaliser but Jürgen Klopp was left scratching his head at how his side squandered two points.
“A point at Arsenal is a good result for most teams in the world but it feels not too good at the moment,” the German, whose side remained in fourth spot a point ahead of Arsenal, said after getting his breath back at the Emirates.
“Arsenal were not in the game apart from 10 minutes.”
Wenger admitted his side had been lucky to only be one goal behind at the break.
“We played frozen with fear and not at our level in the first half. In the second half we played at our level. It was a thrilling game,” he said.
“I am frustrated at not winning but that is the type of game you want in the Premier League.”
Liverpool will doubtless emerge from this thriller the more aggrieved party, having failed to grind out the win from a position of serious strength.
