Well nobody expected that. An extraordinary night of League Cup action! See you all tomorrow.

Liverpool's Jordan Williams: , external"Thanks you all for the messages absolutely buzzing, and to of scored my pen in front of the Kop! Great support as usual!"

Greg, from Birkenhead, via text: Dunno about the penalties, but Lucas scoring twice is definitely a record!

John via text: Awful results for Arsenal and Everton tonight. A lot of work is needed in what remains of this week ahead of the North London and Merseyside derbies for both clubs.

Liverpool manager Brendan Rodgers: "There was great quality on the penalities. Both teams showed great composure. We're pleased to go through after giving away poor goals - lately we've been making too many mistakes.

"I can't fault the character of the players. Congratulations to Middlesbrough, they were excellent. I can see why they are near the top of the Championship. Jordan Rossiter was excellent - he showed great composure for the goal. The finish wasn't easy - he showed great technique.

"It's a very important result. They [the players] want to win in every competition. That adrenalin of winning the game will help the players recover for the weekend derby against Everton."

Southampton manager Ronald Koeman on matchwinner Nathaniel Clyne: "I think he's ready [to play for England]. He has a lot of experience, he is playing very well from the beginning of the season.

"He scored a great goal. I think his performance was very good and I think it's an option for the national coach and I'm very happy to have Clyney in our team because he brings a lot of experience.

"He brings a lot of spirit and I like to have and play with offensive full-backs. He shows that quality and it's very important for the team."

Swansea defender Angel Rangel: , externalA 3-0 versus Everton is a massive result. Fantastic team performance! Well done everyone!

Arsenal manager Arsene Wenger: "We lacked a bit of experience at the back, but overall they did well. We gave a lot and it's frustrating not to be able to score in the second half.

"When you look at the amount of possession we had, we have to give credit to Southampton, they played well and were well organised.

"They abused a bit the fouls in the middle of the park, but they are a good side and they played well tonight. Overall it is frustrating because we gave a lot."

Liverpool midfielder Raheem Sterling: , external"What a night... that's why it's a team game well done the boys. YNWA on to the derby!

Stonewall Sid:, external Brilliant penalties or bad goalkeeping? A bit of both really.

Graham Jack Thirkill:, external Just waiting for the "Wenger Out" brigade to show up. Arsenal did lose after all.

Sam Taylor:, external Now that's a result >> Shrewsbury Town 1-0 Norwich City

Tonight's 14-13 penalty shoot-out at Liverpool was the longest in the history of the League Cup (previous best 9-8 three times - Arsenal v Rotherham in 2004 and Man City beating Stoke and Aston Villa beating Colchester, both in 1982).

The highest in the FA Cup is Macclesfield beating Forest Green 11-10 in November 2001 in the first round.

However, there was also a 14-13 in the Football League Trophy - August 2011 - Dagenham & Redbridge beating Leyton Orient.

Alex McMahon: , externalThat penalty shootout was mad. Good luck to the people attempting to fit the Lpool-Boro game in 80 words for Ceefax.

Liverpool manager Brendan Rodgers: "It was very important to get a result and the players are very happy in the changing room. We're in the hat and that's all we want. This won't affect us for the derby with Everton at the weekend. That's a big game for us, we need to get our league season up and running."

Stoke defender Marc Muniesa:, external Amazing night! I'm very happy with my two goals and for coming on to help the team to win!

This is not an English record as last year Brockenhurst claimed victory in the Hampshire Senior Cup match 15-14 when Andover's Claudio Herbert missed the 30th penalty, the game having finished 0-0.

Remarkably we have video of that. Take it all in.

Southampton keeper Fraser Forster:, external Great team performance tonight! Buzzing to be through to the next round.

So into the last 16 of the League Cup tonight are:

Southampton, Bournemouth, Derby, Sheffield United, Liverpool, MK Dons, Shrewsbury, Stoke, Swansea and Fulham. All eyes on a trip to Wembley.

Stephen via text: Liverpool defending their reputation as penalty kings, and that was without Gerrard and Lambert. Teams won't want a shootout against them in the Champions League.

Andy via text: What a brilliant penalty shootout! The calmness and composure shown by all players was incredible. Both teams should be congratulated.

Cathryn McDowell: , externalThis penalty shootout is the footballing equivalent of the Isner v Mahut 5th set.

Ken Gorry:, external This must be what a German penalty shootout is like.

Paul Williamson:, external Possibly the worst goalies ever. Middlesbrough is excused.

Albert Adomah is given a huge ovation by the massed travelling fans as he trots over with his team-mates. He scored the first time around! What a shootout, but at the end of it it's Liverpool who squeak through.

Albert Adomah! Unlucky, but the end of a remarkable shootout! 30 penalties!
