Number two to Hennessey
Despite being brought to Selhurst Park as a marquee signing last summer, 24-time France international Mandanda has endured a nightmare stay with the London side.
The former Marseille captain was forced to undergo knee surgery in November and has failed to feature for Palace since, despite returning to full fitness in April.
It saw previous manager Sam Allardyce decide to stick with Wayne Hennessey between the sticks and Mandanda will be desperate to leave. The lure of Champions League football at Celtic would prove a lot more tempting than being number two at Palace.
