However, Swansea soon grew into the game and had two good chances in quick succession. Angel Rangel's pass found Nathan Dyer, whose cutback fell to Pablo Hernandez. However, the Spaniard shot well over the bar from a good position.
Just a minute later, Michu - who has scored 17 league goals this season - volleyed wide from six yards out.
The best chance in the opening 45 minutes fell to Nasri, after a perfectly weighted through-ball from Gareth Barry. The French midfielder scuffed his volley though, and Vorm gathered easily.
Swansea City had a penalty shout turned down as the half wore on, but the referee decided Matija Nastasic's challenge on Michu wasn't a foul.
