It seems Liverpool were not banking on a win in normal time and practiced penalties ahead of the League Cup game against Carlisle United.
Ings gifted Liverpool the lead midway through the first half, but parity was restored shortly after and they failed to find the net after extra time.
Therefore, Liverpool needed penalties to scale through and goalkeeper Adam Bogdan was the hero, saving three spotkicks.
“It was great for Adam. We’d practiced penalties the day before the game just in case – and it turned out we needed them to go through,” Skrtel told the official Liverpool website.
“Adam was good. It was his first game, his first game at Anfield, and he’s been doing well. In the penalties, he showed his quality.
“Obviously we expected it to be a different game, but as we know there is no easy game here in England.
“We had plenty of chances to score, but unfortunately we didn’t take them and the game finished with penalties – but we’re happy we went through. That showed we are mentally strong because it’s not easy to play for 120 minutes and then go to penalties.
“We won the game, so I think it was very important for us that we won. It can give us some confidence for the next game.”
After edging past Carlisle, Liverpool will now take on AFC Bournemouth at home in the fourth round.
