Wagner left bemoaning individual mistakes
Nahki Wells's Huddersfield Town crashed to a 5-0 defeat away to Fulham in the Sky Bet Championship at the weekend.
A scintillating display helped Fulham claim only their second win in ten matches as they thrashed high-flyers Huddersfield, who slipped to third in the table.
The home side took the lead after eight minutes when Chris Martin's scuffed shot snuck past goalkeeper Danny Ward.
Defender Tomas Kalas scored his first goal in English football before Lucas Piazon added a third with a bullet header.
Martin scored his second from the penalty spot and Kevin McDonald struck from ten yards to complete the rout.
Fulham had not won at Craven Cottage since beating Newcastle United on the opening day of the season, but produced a fine performance to condemn third-placed Huddersfield to a third defeat in four matches.
The home side took advantage of poor defending to go ahead, as the ball was headed down into Martin's path, allowing him to net his third goal this term.
Huddersfield's defence was once again exposed when Scott Malone's deep cross from the left was brought down at the back post and lashed home by Kalas.
Sone Aluko rode three challenges and stood a ball up for Piazon to power a header in.
Aluko was brought down in the box at the start of the second half, with Martin slotting home the penalty.
McDonald wrapped up a convincing victory when he met Aluko's pinpoint pass to beat Ward for a fifth time and help Fulham climb to eleventh in the table.
David Wagner, the Huddersfield head coach, was left bemoaning individual mistakes made by his players.
“I can leave this game very quickly behind us,” he said. “We don't have to speak about any tactical problems because we had so many individual mistakes that you couldn't get anything against any opponent.
“We were very sloppy when we had the ball and in the end we totally underperformed today.
“I think Fulham were stronger in every position. We had problems everywhere. We made so many easy mistakes.
“This happens in football. It shouldn't but it does and I've always said we will have ups and downs on our journey. This was a down.”
Slavisa Jokanovic, the Fulham manager, said: “We have shown we can play good football and keep clean sheets and that we can be more competitive.
“The job is not done. We need to build on our confidence and philosophy. We are in a learning process and beginning to build some kind of identity.
“We and the supporters deserved that after waiting so long for a win. We have played well and got some points before but we couldn't find a clear way to win games.
Meanwhile, Reggie Lambe was an unused substitute in Carlisle United's 3-1 at home to Crawley Town at the weekend.
Carlisle stretched their unbeaten run to 15 games after an impressive first-half display.
Goals from Jabo Ibehre, Jason Kennedy and Luke Joyce settled the issue before the interval and although Crawley tried to fight back in the second half, Enzio Boldewijn grabbing a late goal, the outcome was never in doubt as the Cumbrians consolidated second place in League Two.
Carlisle soon looked threatening and it took Ibehre just five minutes to head them in front from six yards after the Crawley defence failed to deal with Tom Miller's long throw from the right.
The home side went further ahead in the 28th minute courtesy of Kennedy's seventh goal of the season.
The midfield man was on hand to hook the ball home from close in after Michael Raynes had headed a ball from Mike Jones back across the six-yard box.
Joyce made it 3-0 on the stroke of half-time with the best of Carlisle's goals, a 30-yard screamer which left Glenn Morris beaten all ends up as it flew into the top left corner.
It was a better second-half effort from Crawley, although substitute Jamie Devitt went close to adding to Carlisle's tally with a dipping 20 yarder that Morris was glad to shuffle away for a corner.
Crawley scored a consolation goal in added time when Boldewijn whipped home a low shot from a tight angle.
