Jack Stephens is English defender born in Plymouth on 27th January 1994. Stephens joined Plymouth Argyle at the age of 11. Young Jack had previously been captain of the Cornwall school's under 16 team. Stephens produced a number of superb performances for Argyle's youth side in the Northern Ireland Milk Cup in July 2009. This led to 19 appearances in Plymouth's under 18's during 2009/10, as well as a further five matches in the reserves.
Stephens began training with Plymouth's senior side at the start of the 2010/11 season. He made his first team debut for The Pilgrims on 18th September in a 3-2 win against Sheffield Wednesday, coming on as sub in the closing stages. Stephens' next outing came against Hartlepool on October 2nd when he replaced an injured Krisztian Timar in the 38th minute. He made his first start three days later in the Football League Trophy win at Cheltenham. He played a further three times for Argyle.
On 5th April Southampton signed Stephens on a three year deal for a fee of £150,000, beating off reported competition from Premiership sides Newcastle and Sunderland. The former Pilgrim began the 2011/12 season in style with a fine individual effort against Man Unitedís U18ís on August 27th 2011. Stephens enjoyed a solid first campaign at Staplewood. He made his first team debut as a late substitute at Coventry on January 7th 2012 and looked competent.
