Scott Sinclair opened the scoring when he slotted his second penalty of the campaign in the 10th minute after Potters’ captain Ryan Shawcross, on his 100th top-flight appearance, had made a rash challenge on Wayne Routledge.

Graham then made sure of the win with five minutes remaining as he came out on top in a challenge with Jonathan Woodgate to calmly fire home his maiden strike following a £3.5m move from Watford.

Glenn Whelan went closest for the visitors as he hit the post with a low free-kick, while Jon Walters had a volley athletically tipped onto the crossbar by Michel Vorm to ensure Swansea’s defence remains unbreached on home soil.
