Free agent Elliot Grandin has reportedly been targeted by three clubs in the Championship.
The 26-year-old winger is without a club after leaving Blackpool at the end of last month.
New Blackpool boss Jose Riga is believed to be considering a move to re-sign the Frenchman, but Millwall and Brighton & Hove Albion are also interested in his signature, according to Sky Sports News.
Grandin joined Blackpool for a second spell at Bloomfield Road in February after leaving Crystal Palace on a free transfer, going on to make seven league appearances and scoring one goal.
