Sheffield wednesday boss Stuart Gray believed his side conceded too many free-kicks to be able to beat Leeds United at Hillsborough on Saturday.
The match started off in typically fiery fashion, with both Yorkshire teams aiming to end their mediocre seasons on a high.
Wednesday went 1-0 up in the 36th minute through Maguire after Lloyd Isgrove was judged to have been fouled by Sam Byram on the edge of the box.
The visitors found an equaliser 12 minutes after the break via Charlie Taylor, who capitalised on a lacklustre Wednesday wall to poke home a loose ball from six-yards out after a Luke Murphy free-kick.
Leeds then took the lead through Steve Morison with 18 minutes to play. After a well-timed run and failed first effort, the striker fired home the rebound from close range past Keiren Westwood.
“We gave far too many free-kicks away and if you keep doing that, you will be punished,” said Owls boss Stuart Gray.
“That’s what’s happened and we only have ourselves to blame.
“They got a fortunate ricochet for the equaliser but they reacted the faster.
“It’s disappointing because we had our noses in front but couldn’t build on the Chris Maguire penalty.
“I’m disappointed for the supporters as well because we had around 24,000 in there today.
“I put two forwards on and we were chasing the game but it wasn’t our day.”
