Second-half goals from Jamal Lowe, Ronald, Jerry Yates and Liam Walsh would leave the relegation-threatened Yorkshire side shell-shocked as the Swans would celebrate the biggest win of the Londoner’s era so far.
Williams had called for his side to maintain their standards after securing their status in the second-tier last weekend. Even he couldn’t have imagined what the final scoreline would look like as the Swans were victorious against the Terriers on their own ground for the first time since 2008.
After a close-fought first 45 minutes, the Swans would be much more inventive and assertive in their play in the second period with Liam Cullen hitting the woodwork in a dominant spell.
Huddersfield would have their moments with dangerous centre half Michal Helik crashing a header into the crossbar and David Kasumu spurning a chance when well placed.
It would be the Swans though who would finally get their just deserves with 15 minutes left on the clock. Jamaican international Lowe’s solo run and finish past home keeper Lee Nicholls breaking the deadlock.
Chasing the game the Terriers would implode. Josh Tymon would burst free on the left to square to Ronald for an easy finish on the counter to double their lead.
With the points looking like coming back to south Wales, Yates sealed the victory in stoppage-time tapping in from close range. Further gloss to the scoreline was then added with Walsh curling in a fourth to the dismay of the beleaguered home support.
It would be a fire afternoon for the Swans and their boss would not be able to hide his delight with his side’s performance.

“I’m thrilled with the way the team played,” said Williams.
“They [Huddersfield] are a far better team than they were earlier in the season but now they are under pressure, and they gave us a tough game.
“That’s why I’m so happy because it wasn’t a walk in the park, far from it. The players had to apply themselves.
“We were knocking on the door. We defended incredibly well. People put their bodies on the line, and we came away without the opposition hitting the target.
“We have a duty to the competition to play properly. We have a lot to play for. We have fans to play for, then we have professional pride.”
