Traumatic does not do justice to the impact on Leeds United of Wigan's previous visit to Elland Road when Paul Cook's men won here on a fatal day last April.
Remarkably, they repeated that trick as Joe Williams' left-wing corner was deflected past Leeds goalkeeper Kiko Casilla and into his own net by Pablo Hernandez in the 59th minute.
Once again, Cook's side turned the Championship table on its head by slaying Marcelo Biela's promotion hopefuls and simultaneously boosting their survival prospects.

Let it be remembered that Leeds never recovered from their shock 2-1 home loss to the Latics on Good Friday last term.
From that point, automatic promotion slipped through their fingers before they lost to Derby in the play-offs and were left locked out of the Premier League for a sixteenth consecutive season.
After this result, which left Leeds just three points clear of third place, a crowd of 35,162 left Elland Road with a sickening sense of deja vu.

Bielsa, who saw his side typically dominate possession from start to finish but spurn several goalscoring opportunities, said: 'I have nothing new to say.
'This was an impossible match to lose, but we lost.
'The single question is why we lost a match which we had to win?
'We should have scored at least one of the 15 chances that we had.
'It's clear that the responsibility is on me as manager. But we are talking about a team who are second in the table.'sonos sonos One (Gen 2) - Voice Controlled Smart Speaker with Amazon Alexa Built-in - Black read more from dailymail.....
