He signed a two-year contract with English club Southampton on 7 July 2015. An unused substitute in the first leg, Martina made his Southampton debut in their UEFA Europa League third qualifying round second leg away to Vitesse Arnhem, playing the full 90 minutes of a 2–0 win on 6 August. Three days later, he made his league debut as a half-time substitute for fellow new signing Cédric Soares in a 2–2 draw against Newcastle United. Martina became the first-ever Curaçao international to play for Southampton and the second to play in the Premier League after West Bromwich Albion's Shelton Martis in 2009.
