The Eagles have allegedly clinched a deal for the stopper.
Crystal Palace have completed the signing of Steve Mandana, according to French publication L’Equipe.
The report claims that the Eagles have payed 2 million euros (around £1.5 million) for the services of the France international but does not provide details on the terms of his contract.
Mandanda has reportedly passed his medical – which took place in Clairefontaine – and will now be joining Alan Pardew at Selhurst Park.
The France number two is in his final year of contract with Marseille and it seems Palace did not want to run the risk of waiting for it to run down before signing him so have acted quickly to seal the deal.
Everton and Chelsea were also linked with the 31-year-old, by the likes of the Daily Star, but it now looks like Palace have won the race.
Mandanda will provide welcome competition for Wayne Hennessey between the sticks and the battle for the number one jersey is sure to be an intriguing one.
Both keepers are still taking part in Euro 2016, with Mandanda playing second fiddle to Hugo Lloris as France prepare to face Iceland and Hennessey gearing up to start against Belgium on Friday.
