Crystal Palace's American owners are putting the club up for sale, it has been reported.

The Financial Times says Josh Harris, a billionaire who helped found Apollo, and David Blitzer, a senior executive at Blackstone, who acquired Palace three years ago, have hired PJT Partners - a US boutique investment bank - to advise them on the sale of the team.

Harris and Blitzer, who also own NBA team the Philadelphia 76ers and NHL team New Jersey Devils, have not responded or issued comment about the story, according to city news agency Bloomberg.

Both Wall Street financiers were unveiled by club co-chairman Steve Parish as new co-owners in December 2015.

Parish continued as chairman alongside Harris and Blitzer as general partners, with company accounts showing that Palace Holdco LP (a limited partnership registered in Delaware, where ownership details do not have to be declared) have a controlling stake in the club.
