The Spanish duo scored within two minutes of each other in the second half to stop the rot for Michael Laudrup’s side and prolong the misery of the visitors who find themselves in familiar territory at the wrong end of the table. Roberto Martinez will be cursing his sides luck after Arouna Kone was denied a late equaliser by the offside flag.
It leaves the Latics without a top-flight win since 25th August although they will be wondering how they didn’t leave South Wales with at least a point to show for their efforts.
Clear goalscoring opportunities were few and far between during a tedious first half with Michu going closest for the home side with a volley that sailed narrowly wide in the 18th minute. Jonathan de Guzman then curled wide from 20-yards before Michel Vorm denied Shaun Maloney from close range at the other end.
Thankfully the second half provided more entertainment value for the supporters and they were treated to three goals in four minutes just after the hour mark. Firstly Hernandez was on hand to break the deadlock in the 65th minute and notch his first Swans goal, scoring with a low effort after fine work from Wayne Routledge.
Two minutes later and Michu had doubled the home sides lead, taking advantage of some lax Wigan defending to head home unmarked from a corner. Emmerson Boyce then set up a tantalising final 20 minutes with an outrageous flicked effort that caught Vorm out in the Swansea goal.
Wigan thought they’d snatched a point only for Kone’s effort to be chalked off for offside before goalkeeper Ali Al-Habsi was sensationally denied by Vorm at the death after meeting a corner with a firm header.
