Swansea defender Ashley Williams has dismissed talk about his future as he gears up for Sunday's clash with Chelsea.Williams proved his ability as a top level defender with a superb performance in Swansea's Capital One Cup semi-final first leg win over Chelsea. The 28-year-old will be looking to put in the same performance on Sunday as the Swans tackle the Blues once again. Williams said: "We can get a result there. It will be tough, that's obvious, but we've been there and nicked a win before. "There's a lot of work left still to do this season and we know we have a massive game on Sunday with the pressure we're putting on ourselves and what we've put into it this week. "No-one is looking at their own careers; we're just looking to finish this season strongly."
