Williams wrote in the Daily Mail: "Itâ€™s hard to explain how much Iâ€™m enjoying my football at Swansea. The club has been on an upward curve for a while and itâ€™s just so exciting to be part of that.
"Weâ€™ve had our difficulties, like losing Brendan Rodgers and big players like Joe Allen and Scott Sinclair in the summer, but a new manager and players have come in and done so well. Itâ€™s crazy to think that we will be playing in a major cup final shortly.
"We obviously did well last season, but there was so much change that I donâ€™t think we really thought it would go this well. A few of the lads were laughing about it the other day, that here we are in a final and in the top half of the Premier League."
