BBC Sport's Ged Scott: "Shrewsbury's record capacity Greenhous Meadow crowd - over double this season's home average - has sparked some ironic banter between the two noisy sets of fans, prompted by the Chelsea fans' taunt of "You're here for the first time". Amusing but unprintable response from the Shropshire contingent."

Mitch Mansfield:, external Shrewsbury more comfortable on the ball than many Premier League teams this season. Doing League Two proud, never mind themselves.

Derby's comeback from 2-0 down is complete in fine style - Simon Dawkins cutting in from the left and curling a sumptuous shot into the top corner. Goal of the night.

The competition's leading scorer is at it again - Benik Afobe dispatching his spot-kick with aplomb after Delle Alli had been brought down by Craig Alcock.

Shrewsbury mix things up and send on winger Jordan Clark in place of Bobby Grant. The ex-Barnsley forward has 23 minutes to make an impact.

The Anfield Kop is cranking up the volume as their heroes press for the opener. Liverpool midfielder Philippe Coutinho fires into the midriff of Swans keeper Gerhard Tremmel in the first opening of the second half.

An inspired fightback from Derby who have fought back from two goals down. Simon Dawkins gets to the whitewash and pulls the ball back for Johnny Russell to gleefully smash home.

Do you know when you play 5-a-side and there's one player who is just head and shoulders above everyone else? Smashing in shots left, right and centre. That man is Didier Drogba tonight. He blasts another effort at the Shrewsbury goal which is too hot for Jayson Leutwiler to handle but the danger is cleared.

Andy: Rickie Lambert is fluffing his lines tonight, he has a real chance to lay down a marker tonight and stake a claim for a starting place. Mario Balotelli isn't setting the world alight, so Lambert could put himself firmly in the frame with a good performance. He needs a big second half.

No Mario and no Wilfried. Both teams as you were as Swansea kick off the second half.

A massive penalty shout for West Brom is waved away and manager Alan Irvine looks perplexed on the touchline. A cut-back from Brown Ideye prompts Bournemouth central defender Tommy Elphick to slip and his momentum is stopped as he falls on the ball with his hand making clear contact.

It looks unfortunate but clear-cut.

"Liverpool dominated possession in the first half but a lot of that was played in front of Swansea. That big opportunity for Lazar Markovic, where he sliced wide, was the biggest chance of the game.

"But Swansea came back into it, created a few problems, but they need to see a bit more from Dyer, Montero and Gomis - certainly on the counter attack.

"Bony could be an option for Swansea, but they saw this as an opportunity to give him a rest. As for Balotelli coming on, I'm not too sure. Lambert has had very little impact. I'd like to see Lambert play between centre halves a little bit more."

Sheffield United should be in front at Stadium MK. Marc McNulty's cross from the right drops perfectly for Stefan Scougall, who is unmarked in the box, but he misjudges his header and puts it over the bar.

"Micky Mellon has head in his hands. He must have thought from his angle it was in. Shrewsbury are not giving this up without a fight. The attitude of the players is fantastic and Micky will be so proud of them."

Shrewsbury are still battling and they almost level matters - Jean-Louis Akpa Akpro's shot taking a wicked deflection and smashing into the post with Petr Cech wrong-footed.

Rian Hoskins:, external Didier Drogba is back up to the pace of English football and is now on great form. Considering he is 36 it shows his natural ability.

Harry Pannell:, external Three goals in three games. Is Drogba really past his best yet?

Mark Hill:, external Drogba again? Is he really 36?

Andre Schurrle almost doubles Chelsea's lead with a rasping shot which goes just over the bar. Incidentally, before the visitors took the lead, a cheeky Shrewsbury steward was caught on camera asking for John Terry's autograph. He got it.

BBC Sport's Ged Scott at Greenhous Meadow: "You always got he impression that Chelsea were toying with the Town - and just three minutes into the second half they have their breakthrough as a neat slick exchange involving Salah opens the door for Drogba to run on and fire home left-footed to the right of Jayson Leutwiler. Are the floodgates now going to open?

It was a long, long night at Anfield last month when Liverpool and Middlesbrough needed 30 penalty kicks to separate them in the third round. And at this rate, with Liverpool misfiring, it could be another late one. Don't let the kids go to bed yet.

"It just shows you how much it means to Didier Drogba with his celebration. Chelsea manager Jose Mourinho will have told his players to wait for those moments and when they come along take them. And that's exactly what Drogba has done."
