Sky Sports understands Elliot Grandin has agreed a deal to join Crystal Palace after impressing on trial.
Former Blackpool winger Grandin is available on a free transfer after leaving Bloomfield Road earlier this summer.
The 25-year-old linked up with Palace earlier this month for pre-season training and has featured in a couple of friendlies.
Palace boss Ian Holloway is a big admirer of Grandin having signed the Frenchman during his time in charge of Blackpool.
Grandin is set to sign a one-year deal with the option of a further 12 months as Holloway continues his plans to strengthen his squad before the start of the new season next month.
