Sheffield Wednesday delivered their worst performance of the season as they crashed to a 3-1 defeat at managerless Charlton Athletic this afternoon.
Goals by Johnnie Jackson, Simon Makienok and Reza Ghoochannejhad halted the Owls' 11-match unbeaten run and stretched their winless streack against the Addicks to six.
Fernando Forestieri, named the PFA Fans’ Player of the Month for October, notched his fifth goal in 10 Owls starts to give Carlos Carvalhal's troops hope of staging a late comeback but it wasn't to be.
Carlos Carvalhal, the Owls head coach, made one personnel change, handing Gary Hooper his full debut up front, dropping Lucas Joao to the bench.
But Charlton, lying second-from-bottom before kick-off, caused the visitors plenty of problems in the skirmishes and it took a superb challenge by Sam Hutchinson to prevent Johnann Gudmundsson from getting a clear sight at goal in the 11th minute.
Wednesday lacked penetration in the final third and Fernando Forestieri's scuffed drive was comfortably gathered by Stephen Henderson after good approach play by Wallace.
Carvalhal's men had another big let off when Reza Ghoochannejhad glanced Johnnie Jackson's corner inches wide.
Hutchinson had to be alert to cut out a dangerous delivery by Addicks substitute Tareiq Holmes-Dennis as the hosts continued to carry the greater threat.
Their patience paid off when Jackson headed in Charlton's first goal in over seven hours. It is the fourth time Jackson has scored against the Owls, who looked rattled.
Wednesday's misery was compounded when Hutchinson collected his 10th yellow card of the season on the half hour mark, meaning the defensive midfielder will miss their next two fixtures.
Gudmundsson, looking lively at the tip of Charlton's diamond, fizzed a shot over from long range before setting up Makienok for the Addicks second on the stroke of half-time.
It took some fine defending by Morgan Fox to stop Forestieri from converting Kieran Lee's cut back as Wednesday tried to reduce their arrears.
Following a disappointing opening 45 minutes, Carvalhal made a double change at the interval, taking off skipper Glenn Loovens and Hutchinson and throwing on Vincent Sasso and Lucas Joao.
Forestieri, switched to the left flank with Barry Bannan moving inside, was cautioned after a clumsy tackle on El-Hadji Ba, who superbly protected Charlton's back four.
And the contest was put out of Wednesday's reach in the 55th minute when Ghoochannejhad tapped in inside the six-yard box following a lovely move involving Makienok and Fox.
Charlton almost grabbed a fourth through Gudmundsson, who rattled the crossbar with a fierce free-kick from distance.
The Owls kept battling and Joao, named in Portugal's senior squad for the first time yesterday, dragged a low effort off target after out-pacing Naby Sarr.
With 17 minutes left, Wednesday grabbed a consolation, Forestieri steering in Lee's inviting centre to claim his fifth goal in 10 starts.
Forestieri's strike perked Wednesday up and Joao headed off when well-placed after intricate wing play by Wallace.
The Addicks got a little jittery but could have restored their three-goal cushion in the dying minutes after substitute Makienok latched on to Ademola Lookman's neat pass but he fired straight at Westwood.
In the dying embers of the contest, Lewis McGugan volleyed over and curled a free-kick narrowly off target before Bannan limped off with an injury to compound Wednesday's frustration.
