46' 
We begin again and I'm pleased to report that Koscielny is back out too. On reflection, it was a definite red.
46' 
 GOAL Ngog smashes one into the roof of the net! A decent ball from MAscherano, Ngog turns away from Vermaelen and lashes one past Almunia.
47' 
What a start to the half for Liverpool. They've something to hold onto now and Arsenal have to push on.
48' 
CLichy is penalised for a bump on Kuyt and Liverpool have a free kick wide right.
49' 
Gerrard delivers and Skrtel gets there before Almunia but can't direct his header on target. Dodgy keeper.
50' 
Eboue slams a cross right at Reina, who holds firm.
51' 
Johnson's persistence wins him a corner.
51' 
Arsenal are penned in here as the corner goes deep to Jovanovic, before Diaby nods behind his cross for another corner.
52' 
Arsenal clear their lines properly this time after Jovanovic fails in a diving attempt to make contact with a high ball.
53' 
Johnson very nearly works space for a shot after a lovely move to beat two players. Now Ngog wins the free kick. Arsenal are rocking here, and they've got the extra man.
55' 
Gerrard's delivery finds Ngog and he should really have made it 2-0.
56' 
Looks like Walcott and Rosicky might be coming on.
57' 
Wilshere clips two crosses into the area but they are dealt with comfortably by Liverpool.
58' 
Nice football from Arsenal on the edge of the box and Nasri wins a corner after his shot is deflected.
59' 
Nasri's corner comes out to Wilshere but his effort is weak.
60' 
 Walcott and Rosicky come on for Eboue and Wilshere.
61' 
Walcott's first involvement is to win a corner.
62' 
Diaby turns in a terrible ball that everyone watches run out of play.
62' 
Chamakh lays off to Arshavin, who slips, much to the delight of the home support.
64' 
Ngog chases a long ball but inadvertently uses his hand to nick the ball away from Clichy. The ref spotted it.
65' 
 Maxi Rodriguez is coming on for Jovanovic.
66' 
Kuyt nutmegs Clichy and rolls the ball across the face of goal but no-one in a red shirt is advanced enough to tap home. An embarrassing moment for the Arsenal left back.
67' 
Terrior like work from Mascherano, who won't let up on Diaby. Liverpool win possession, and at the moment, they look like they want it far more.
68' 
Rosicky makes space for a decent cross and Vermaelen heads wide from eight yards out. Should have done much better.
69' 
Ngog looks confused as the ball lands at his feet, he must have thought he was offside. Arsenal break and Nasri's shot is blocked by Skrtel.
70' 
Torres is being primed as the Kop erupts.
71' 
 A yellow for Gerrard after a lunge on Chamakh. Free kick 25 yards out and central.
72' 
Walcott and Nasri over the free kick.
73' 
Walcott fires one goalwards and Reina is forced into a smart save. From the corner Koscielny can't connect with Vermaelen's flick.
74' 
 David Ngog goes off for Torres, who gets a noisy reception.
75' 
And in response, Wenger now readies Robin van Persie.
76' 
 Diaby makes way for Van Persie. Wenger's final throw of the dice.
77' 
Van Persie looks to slide in Chamakh but Carragher is there. This will be backs to the wall for Liverpool you feel, as Torres tests Koscielny for pace.
78' 
 Lucas is coming on for Mascherano, who looks like he's tweaked something.
79' 
Arsenal win the corner as Agger clears a through ball.
80' 
Walcott and Rosicky work a nice situation but the former shoots from a tight angle when he should have crossed.
81' 
Agger is down and staggering off. He got a whack in the face about ten minutes ago and looks a little concussed. Liverpool down to nine men.
82' 
Sagan turns in an awful ball and Arsenal are running out of time and ideas. They've been seriously poor today.
83' 
Torres turns Koscielny and goes down under a tug but Martin Atkinson denies him a penalty. It would have been a soft award.
84' 
Agger is still off the field and looks very groggy. He's preparing to come back on it looks like but I don't think he's too chuffed at the prospect.
85' 
 Rosicky is booked for clattering Gerrard, when perhaps it should be the Liverpool captain getting his second. Both are alright to continue after a meaty collision.
86' 
The best bit of football from Arsenal as Rosicky gets the ball from Van Persie and shoots but Reina makes a first class save.
87' 
An almighty scramble in the six yard box as Nasri meets a cross at the back post. Skrtel eventually clears as Walcott desperately tried to stab the ball home.
88' 
Vermaelen nods wide from an Arsenal corner but the whistle had gone for a foul on Reina.

93' 
Gerrard blasts the free kick goalwards and Almunia palms it clear.
94' 
Arsenal break from the corner but Chamakh can't collect Arshavin's ball forward.
94' 
Walcott scampers down the right and crosses, but Vermaelen manages to head it backwards.
95'
Koscielny gets a second yellow for handball, and that is very harsh.
96' 
Full time and an entertaining second half. Arsenal were poor but they've got out of jail after an error from Pepe Reina. Both teams will probably be happy with a point when the dust has settled.
