But they found the second half tougher going as Wednesday successfully stifled their creativity.

And the South Yorkshire side were given their rewards when Murphy beat Kiko Casilla from a narrow angle.

Nuhiu wrapped the points up four minutes into stoppage time after Adam Reach teed him up.

It left Leeds six points ahead of third-placed Brentford in the race for automatic promotion.

Luke Ayling and Helder Costa both had chances for the hosts inside the first 10 minutes.

Massimo Luongo headed well wide from a Barry Bannan corner after 10 minutes with a free header.

Harrison volleyed wide from close range when Kalvin Phillips picked him out.

Bamford had a header chalked off five minutes later after Mateusz Klich was ruled offside in the build-up.

Cameron Dawson brilliantly tipped a Harrison shot around the post in the 27th minute, before Julian Borner failed to keep a 20-yard half-volley down.

Dawson saved a Bamford shot at his near post and Costa smashed over in stoppage time.

Bamford shot over three minutes after the restart after Costa got to the byline and picked him out.

Sam Winnall just failed to get on the end of Murphy's ball across goal a minute later and then fired a brilliant chance over after a Morgan Fox header fell kindly.

Costa failed to find the target as Leeds were once again restricted to shots from long range.

Dawson saved a curling effort from Klich four minutes later, before Casilla had to turn away Murphy's goalbound inswinging corner.

Reach fired over with a cross-shot in the 74th minute, before Harrison missed the target with a header with 10 minutes to go.

Murphy's low shot squirmed past Casilla in the 87th minute to give Wednesday the lead, and it was game over when Reach got in behind the defence and set up Nuhiu deep into stoppage time.
