The 22-year-old winger returns to the ground where he made his first start for Southampton in a Capital One Cup tie back in 2012, which Saints won 5-1.

Isgrove, who has featured on six occasions for Martin Hunter’s Under-21s this season, could be involved in as many as 12 games during his time at Oakwell.

The loan move is the third of Isgrove’s career, having spent time with Peterborough United in League 1 during the 2013/14 campaign and enjoyed a spell with Sheffield Wednesday in the Championship towards the end of last season.

Lee Johnson’s Barnsley currently sit 19th in League 1 with 14 points from their opening 13 games of the campaign.

Isgrove goes straight into the Tykes’ squad for their home game against Fleetwood Town this afternoon.
