Nottingham Forest have Barnsley man Callum Styles on their "radar" as they build a squad for the Premier League.
The 22-year-old left-sided midfielder has been a previous target for the Reds having reportedly made a move for him in January.
Styles has been one of the Tykes' stand-out players over the last two seasons, including this term when he scored three goals and contributed two assists in 46 appearances across all competitions as they were relegated to League One.
