Bit surprised Manchester City Manuel Pellegrini has taken David Silva off  - maybe the Spanish magician was tiring after his midweek Champions League exertions,

Wilfried Bony on - who has a decent record as a penalty taker.

"Sergio Aguero has had three good chances today and you would have expected him to score one of those."

Chance for Sergio Aguero! James Milner duffs his headed pass back to the keeper, brilliantly read by Sergio Aguero and on the stretch he can only toe it over the bar!

I asked when was the last time you saw a good period of extra time - this is it. 

Liverpool really turning it up now as Divock Origi is close to meeting another James Milner cross...

A begloved Wilfried Bony is on for David Silva, with the air of a man who intends to take a one-step penalty...

"What a period of play! Good save from Caballero. It is a save he should make, but it was brilliant, brilliant pressing from Liverpool."

INJECTION OF LIFE: Daniel Sturridge rises to get on the end of a cross but he collides with Adam Lallana. Yaya Toure then counters and looks to break though, but Kolo tackles him.

Liverpool come again, James Milner crosses and Divock Origi's header is saved by Willy Caballero!

A brlliant 60 seconds...

sViera: If Liverpool win, it is completely and utterly undeserved. But I'll take it

Stick Gangsta: Mignolet's man of the match. i think...

Francis Edwards: People knock Mignolet for the odd mistake, but to be honest he's been phenomenal today. Keeping Liverpool in it!

"I am near the Liverrpool dugout and behind me are Martin Skrtel and Dejan Lovren and the language has been very entertaining. They are kicking every ball, they are taking deep gasps of breath."

Simon Mignolet to win it in a shootout? That's the vibe. 

We are back under way!

"If Liverpool lose this game, Simon Mignolet will be remembered for the mistake but he has kept Liverpool in this game. It would have been over after 90 minutes if not for him."

Extraordinary afternoon for Simon Mignolet. One clanger but three brilliant saves!

Simon Mignolet again! Sergio Aguero is played in, he shrugs off Lucas and tries to dink it past the Belgian and into the net - but Mignolet throws up a hand and turns it away!

Great save!

"Wherever he plays he'll give you 7/10. He's a superb professional and has had a great career."

When was the last time anyone saw an exciting period of extra-time? So often it's a stale half hour. Give golden goal another run out...

Sergio Aguero is fouled by Lucas, who has had a very tidy afternoon at centre-back actually. Manchester City having a little spell of pressure now as David Silva wins a corner.

Marwan Nawaz: I just can't see Raheem Stirling having a career at City under Pep - he is nothing more than average

Colin Reardon: You'd think that Sterling was still on Liverpool's payroll the way he's helped them today!

Bob Sleight: Sterling should try shaving off those sideburns... maybe that will help him

Adam Lallana goes in wildly on Pablo Zabaleta, who doesn't even flinch and the potential incident is defused. Rash from Lallana though, and needless too. The game hasn't got going in extra time.
