Just like in the Premier League, both of the Hatters’ goals came from set-pieces, and the manager was happy once more with his team’s ability from set-ball situations on another satisfying day at the office on Merseyside.

“The two games we’ve won here we’ve shown the importance and value of set-pieces and that’s credit to the lads and the staff who put a lot of time and effort into them,” said Edwards afterwards.

“To be fair we also had some good chances from open play and should have taken one or two.”

It was two substitutes that combined for the winner at the death with Cauley Woodrow powering home following Luke Berry’s corner to book the Hatters spot in the next round of the competition.

On the contributions of his substitutes, Edwards added: “It was a real good moment for those boys to be on at the end and celebrate with our supporters. It’s nice, especially for Bez to be involved in that moment.

“I’m delighted for Cauley and all of the lads that came on. All five had an impact. I keep saying how much value we have in the whole squad and we know we need to keep everyone focused and fit in order for them to make an impact when they come on.”
