Swansea City's record signing Wilfried Bony marked his debut for the club with a brace, as the Welsh side built a commanding first-leg lead against Malmo in the Europa League third qualifying round.

The £12m arrival from Vitesse Arnhem scored twice in four second-half minutes, before fellow new boy Alejandro Pozuelo also found the net late on in a 4-0 win.

Last season's top scorer Michu had earlier broken the deadlock for the Swans, capitalising on a defensive slip-up to fire home from 12 yards on 36 minutes.

Nathan Dyer created the first of Bony's two goals. The former Southampton winger got free down the left and dinked in a good cross that the Ivorian headed powerfully into the net.

Bony's second was a simple rebound, which was presented to him after Michu had struck the post.

Swansea were tremendous from start to finish and their extreme superiority was reflected on the scoreline thanks to Pozuelo's 18-yard half-volley, which came five minutes from time.
