Match ends, Sheffield Wednesday 0, Norwich City 4.
Norwich City manager Daniel Farke says his side must not get carried away after going top of the Championship.
The Canaries thrashed a poor Sheffield Wednesday side 4-0 - their first win at Hillsborough in almost 17 years.
"We all have our feet on the ground," Farke told BBC Radio Norfolk.
"We know we have had a decent start, and to be there after 16 games with 30 points already is outstanding."
"But we know we can't relax and we can't enjoy ourselves too much. We need at least six more wins to at stay in this league.
"If we relax just a bit and think about the beach or whatever we won't win any points, so it's important we go for them."
Ten-minute goal spree seals win
Norwich missed a golden chance to lead after five minutes when Mario Vrancic saw his tame penalty easily saved by Cameron Dawson.
But they took advantage of a shaky Wednesday as they scored three times in a 10-minute spell soon after half time.
Teemu Pukki - playing in the league for the first time in three weeks after injuring his hamstring while playing for Finland - put City ahead as he converted after Vrancic's shot was deflected into his path.
Static defending then allowed Emiliano Buendia time to turn and fire home before Pukki tapped in the third from Max Aarons' ball into the box.
Late substitute Dennis Srbeny made it 4-0 with his first touch after Dawson's poor clearance fell to Vrancic, who played the substitute in.
Norwich have won eight of their past 10 league games, including a run of four consecutive victories, while the loss increases the pressure on Wednesday boss Jos Luhukay as his side have now lost four in succession, conceding 12 goals in the process.
Booing Owls fans chanted the names of out-of-favour duo Keiren Westwood and Sam Hutchinson after a performance that lacked confidence and cohesion.
Norwich last won at Wednesday in December 2001, losing 5-1 on their previous two visits to Hillsborough, and they could have gone behind after three minutes when Josh Onomah blazed over from close range.
But Norwich had a number of chances to add to their lead, the best arguably with 15 minutes left as a mazy run from Onel Hernandez forced Dawson to palm the ball behind.
Sheffield Wednesday manager Luhukay said the performance was "not good enough".
"We must be very quick to bring our best performances back," he told BBC Radio Sheffield.
"Before the international break it was very positive, and now it is negative - that is football and you must fight against this.
"Sometimes it looks like we don't have the stability to clear at moments when you can clear. At this level and in this league that's not possible and our opponents profited from the mistakes that we made."
