Swansea's inability to take their chances means they still await their first Premier League goal and win after drawing 0-0 with Sunderland at the Liberty Stadium.
Record signing Danny Graham headed their best chance wide when unmarked inside the box, while the striker forced two fine saves from Simon Mignolet and Scott Sinclair stuck the bar.
Sunderland also continue to wait for their first win this term and this result will have done little to lift the pressure on boss Steve Bruce. The Black Cats threatened through Asamoah Gyan early on but the Ghanaian fluffed their best chance when he miscontrolled a Jack Colback pass, while debutant John O'Shea hit the bar.
