Two late goals from Michu earned Swansea a shock victory over a below-par Arsenal at the Emirates Stadium.

After drawing their last two games on the road Arsene Wenger's men were hoping to get back to winning ways on home soil, but they were left stunned by devastating late double from the Swans' leading scorer.

The 26-year-old Spaniard was a virtual unknown when signed by Michael Laudrup from Rayo Vallecano for £2 million in the summer, but is quickly forging a fearsome reputation as one of the Premier League's deadliest hitmen.

How the Gunners could use a goalscorer of this ilk as they once again looked blunt in attack and struggled to contain the visitors sharp passing and movement - a trait that used to be their hallmark - as a collective groan rang around the Emirates at the final whistle.

They had plenty of warnings before Michu's double hammer blow at the death and should have been alerted when Angel Rangel nipped in behind a back four that was bailed out by a double save from Wojciech Szczesny.

Thomas Vermaelen then denied Nathan Dyer with a lunging block before Gervinho went close for the hosts, the Ivory Coast forward finding himself just inches from connecting with Carl Jenkinson's cross.

After the break Santi Cazorla tested Gerhard Tremmel with a low drive, while Szczesny saved again from Rangel.  Mark Clattenburg then waved away appeals for a penalty after substitute Olivier Giroud was brought down by Chico Flores in the penalty area.

Vermaelen then planted a header straight at Tremmel and their lack of potency up front was punished with two minutes left on the clock when Michu played a neat one-two with Luke Moore before curling the ball past Szczesny.

And a superb afternoon for Swansea was wrapped up when the Spanish striker took advantage of  Jenkinson's poor back pass to score and leave Wenger pondering another looming crisis.
