Lacey is out of contract at Huish Park next month and although Yeovil are desperate to tie down the centre-back to a new deal his suitors have been alerted to his possible availability on a free transfer.
Lacey's form at Yeovil has not gone unnoticed among rival clubs with the likes of League One duo Charlton Athletic and Oxford United as well as League Two pair Coventry City and Bristol Rovers all expressing an interest in his services.
Lacey began his career at Luton Town before joining Yeovil in the summer of 2015 and he has made 72 appearances for the Glovers since his arrival.
