Erwin Mulder believes victory over Sheffield United shows just how much fighting spirit there is in the Swansea City dressing room.
The Swans claimed a 1-0 win over the high-flying Blades at the Liberty Stadium thanks to Oli McBurnie's 11th goal of the season.
It settled a tense and hard-fought encounter where there was little between the sides and extended Swansea's unbeaten run to five games; the longest such sequence of Graham Potter's tenure to date.
It also moved them up to ninth in the Championship table, six points off the play-off places.
And goalkeeper Mulder was delighted to see the hosts dig in and prevail in a nip-and-tuck contest.
"It's a big victory for us. We dug in as a team," said the Dutchman.
"We were not so good on the ball but we fought as a team and if you fight as a team you can achieve something, and we did in this game.
"We defended the box really well as a team with everyone chasing them down. Every cross we defended well and it's a big plus for the team to have a victory from this one."
Mulder made two vital saves while the game was goalless in the first half, and they would prove crucial in the final outcome.
The big keeper firstly got down quickly to save Billy Sharp's effort with his left foot after United had found room down their left side.
He then reacted sharply when David McGoldrick's strike hit Cameron Carter-Vickers and cannoned goalwards.
It preserved a first league clean sheet since the win at Bolton in November, and the 29-year-old says the shut-out is a big confidence boost.
"It was a cutback and I saw there was somebody on my left side who I thought would get it," said Mulder of Sharp's effort.
"But their number 10 I think it was who got the ball, and you just have to hope you can put yourself in a good spot to make a save and I did.
"So it was a good save and it has been a while since we have kept a clean sheet in this competition, so I am very glad for the whole team that we managed to get one here.
"You always want the three points but to have a clean sheet is good for the team and the confidence."
