Jason Cummings is the first lower league player to score a brace from the bench in the FA Cup against Premier League opposition since Hull City's Nick Barmby against Wigan in January 2011.

That's it - all over! Shrewsbury have come from a goal down to earn a replay at Anfield against the European champions.

Josh Laurent starts to run and I think he gets cramp in the back of his legs so goes for goal and nearly catches Adrian out there.

From the set-piece, Jason Cummings heads over by a few inches. Adrian launches it long, looking for Mohamed Salah but Mx O'Leary comes off his line to sort it out.

Dejan Lovren curls a nice ball in. Headed away. Josh Laurent brings it out and drives down the line.

Shrewsbury take a quick throw-in and Laurent goes for goal from long range. He almost catches Adrian out at the near post! What an effort!

Fixture congestion is not going to get any easier if Shrewsbury can get through this but Liverpool will only have themselves to blame. They have been complacent. Stopped playing when they were 2-0 up.

Liverpool take a quick throw-in. Yasser Larouci's cross is blocked by Daniel Udoh. Another throw-in...

Just too much on the ball from Mohammed Salah as he tried to steer it towards the goal.

Will this goal be enough to seal a replay at Anfield??

OHHHH you'd put your money on it.

Mohamed Salah's movement is excellent in the box and Roberto Firmino picks him out with an accurate lob from the left.

Salah is unmarked but can only head it wide of the far post.

Heading into stoppage time... Jurgen Klopp is gesturing frantically on the sidelines. Liverpool are starting to turn up the heat.

Mohamed Salah tries to link up with Divock Origi but it's just about cleared. A long ball from Fabinho then comes all the way through to Roberto Firmino and he's denied from close range at the near post!

It rebounds into the middle and Curtis Jones is sliding in as he tries to poke it home but Ro-Shaun Williams makes an excellent last-ditch challenge.

I think the Shrewsbury players have got to not worry about the reputation of the players that have come on the pitch and keep doing what they are doing. It's a bit daunting though isn't it, when you see Mohamed Salah and Roberto Firmino coming off the bench.

Another ball is whipped in from the right by Donald Love. It flicks off Daniel Udoh and appears to hit Fabinho's arm.

There's plenty of appeals for a penalty but the offside flag is up again anyway.

Will Happen: Shrewsbury playing like they are the Prem team now! Oh, that own goal...

Qaaltagh: I know he gave away the penalty, but Larouci is playing with a lot of composure right now. Think the atmosphere in this stadium has startled some of the kids - they genuinely need to get it together and stop playing as though they were guaranteed a win from the get go.

Here's Jason Cummings' first.

Surely Mohamed Salah and Roberto Firmino can come up with a bit of magic to regain Liverpool's lead?

The Shrewsbury players were just looking over at the bench and thinking: "He's not coming on as well, is he?"

Here come the changes.

Daniel Udoh is on for Shrewsbury. Shaun Whalley is off.

And on comes Roberto Firmino for Liverpool. He replaces Takumi Minamino.

Yasser Larouci tries to use his pace to beat Josh Laurent but he can't get past him. Shrewsbury switch it to the left and Neco Williams comes sliding in in the box. He's lucky because the offside flag goes up again.

Pressure, pressure, pressure.

Sam Score: Sometimes changing the team so much isn't such a great idea, lucky last round and could get beat this round if not careful

John Burns: Can LFC please offload Dejan Lovren before the end of the week. Persistent liability
