Brendan Rodgers said a tactical switch at half time was vital to Liverpool picking up a crucial three points away at Swansea City.
After a poor first half, Rodgers tinkered with the formation at the break, and the Reds ran out 1-0 winners after a third consecutive league goal from Jordan Henderson in the second half.
Rodgers said: “It was a wonderful demonstration of the character and resilience in the team, especially [after] how we played in the first half.
“Any system you play in the game doesn’t work unless you have that ability to work, and we just weren’t anywhere near it in the first half. But that resilience and character kept us in the game.
“We knew we were going to be better in the second half, we changed the structure of the team a little bit and then I thought in the second half we really dominated the game.
“People who know me and have watched my teams regularly from when I was a youth coach, my teams have played 4-3-3 and 4-4-2 diamond.
“If you look at Swansea tonight, they were a diamond and we were a box in midfield, and they got between us quite well I felt because they’ve got good players and they passed it well.
“We’ve prepared that in training for if we have to flip and you see the difference it can make. The players went smoothly into it.
“You push the sides further up, so it’s a 3-4-3 but in a different format. We pushed Raheem [Sterling] higher up the pitch onto the full-back, [Alberto] Moreno went right high and then the diamond occupies the spaces in midfield.
“They play with two front players, but we still go three versus two at the back and then that allows us to have the extra numbers. It worked well for us.”
