Chelsea defender Levi Colwill is wanted by Leicester City and Southampton.
The 19-year-old centre-back had an impressive season on loan at Huddersfield Town last season and has also attracted interest from Everton.
Leicester are particularly keen but need to offload Jannik Vestergaard first.
The defender, who is a product of Chelsea's academy, spent last season on loan at Huddersfield Town in the Championship as the Terriers narrowly missed out on promotion to the the Premier League.
Colwill made 32 appearances on loan at Huddersfield last season, helping the side to the play-off final before they lost 1-0 to Forest at Wembley, in which he scored an own goal.
