Defender Jason McCarthy has become Barnsley's second summer signing after joining on a three-year deal from Premier League Southampton.

The 21-year-old, who can play at either right-back or centre-back, made one appearance in the top flight for the Saints but has impressed in loan spells at League Two Wycombe Wanderers two seasons ago and Walsall last season, as he played every League One match. He was voted Player of the Year by fans after both spells and has 92 career appearances with seven goals.

He joins Scottish midfielder Stevie Mallan as the new arrivals at Oakwell for the 2017/18 Championship campaign.
