Liverpool played out a pulsating encounter with Arsenal at Anfield with the match finishing 3-3.
Roberto Firmino struck twice as he led the line for the Reds but two goals which could be seen as the fault of Simon Mignolet from Aaron Ramsey and Olivier Giroud twice allowed the Gunners to level the game up in a breathless opening 25 minutes.
After the break Giroud struck again and with Liverpool seemingly running out of ideas - having introduced both Christian Benteke and debutant Steven Caulker, it looked as if Arsene Wenger's side were going to leave with all three points, until Allen profited from Benteke's knockdown in stoppage time to rescue a point for Jurgen Klopp's men.
The result leaves Liverpool in ninth in the Premier League table ahead of the weekend's clash Manchester United as tonight's display showed Liverpool at their good, bad and ugly.
Here is how the men on display rated:
Simon Mignolet - You have to think he should do better on both goals in the first half. Just really poor and ultimately cost Liverpool points - 3
Nathaniel Clyne - Got up and down, wasn't exposed that much. Not sure whether his booking was brainless or clever - 6
Kolo Toure - Seemed to relish battling Giroud more than his central defensive partner. As solid as you can be when you concede three - 6
Mamadou Sakho - Looked rusty again, nowhere near his best and vindicated all those that say he's terrible on the ball - 3
Alberto Moreno - Offered a constant threat on the left, needs to develop when it comes to composure though - 6
Emre Can - Opening goal comes from a bit of chaos of his doing, second equaliser from bewilderingly trying to play out from the back when there wasn't one on. Not sure he has the composure to play regularly in these kind of games - 4
Jordan Henderson - Not sure what to make of Henderson's performance. The team seemed better for him being there even if he didn't do anything outstanding - 6
James Milner - Asked to do a job on the left and seemed to cause problems for the Arsenal back line by getting in and behind. Unfortunate in build-up to their third - 5
Jordon Ibe - Quiet first half, poor second half. Really needs to offer a lot more consistently - 4
Adam Lallana - Led the line well with Firmino as his movement caused Mertesacker problems early on, but then faded - 6
Roberto Firmino - Two very well taken goals that are typical of a top class forward. Unlucky not to get third before half time and was Liverpool's biggest threat at times of toil. His best display in a Liverpool shirt - 9
Christian Benteke - Still not linking up all that well with teammates, telling he and Henderson were in conversation at the end about runs he should make. Crucial knockdown for equaliser - 6
Joe Allen - Looked more at home than Can, and got the crucial equaliser. The perfect cameo display. His outlandish mark of 1000 is because I put this on Twitter immediately afterwards
Steven Caulker - Bet he didn't think he'd be starting his Liverpool career coming on up front. Had little time to make an impact - N/A
