Sunderland Association Football Club Current Players
* - On loan at Wycombe Wanderers
Billy joined Sunderland from Chelsea on a scholarship contract in the early stages of the 2010-11 season.
The England youth international wasted no time in making progress on Wearside, scoring five goals in his first eight games.
He won a call-up to the first-team squad in February 2011 while still with the under-18s and rounded off 2010-11 by leading the youth team in goals with 13 in 23 games.
Billy also broke into the reserves and took the next step in his career in 2011-12, joining AFC Wimbledon on loan for six months.
He was a huge hit at Kingsmeadow, scoring three goals in 20 games and walking away with the club’s Young Player of the Season award despite only joining half-way through the season.
Meanwhile Billy also fitted in 15 games with the development squad, scoring twice.
Like a number of his young colleagues, Billy was called up for the Peace Cup tournament in summer 2012 but didn’t play. However, he did make his debut in the 1-0 friendly defeat at Hartlepool soon after returning from the Far East.
Billy joined Woking on loan in October 2012, enjoying a successful spell before making his first-team debut for Sunderland as a late substitute against Spurs on the final day of the season.
He headed out on loan again early in the 2012-13 season, linking up with League Two side Wycombe Wanderers.
