Williams added: "I haven't had much luck at Fulham.
but didn't manage to play any first-team football so hopefully I will get a chance here and things will work out for me and the club.

Australia-born Williams joined Portsmouth in August 2011, making his debut against a Middlesbrough team that included his brother Rhys,
He made six appearances for the club, his last coming in the 4-0 defeat by Chelsea in the FA Cup, before Fulham took advantage of Pompey's financial crisis However, until his Oxford debut he had not played a first-team game since then.
