Released Liverpool fullback Jose Enrique is fielding Premier League offers.
The Croydon Advertiser says Palace have reportedly joined Premier League rivals West Ham and West Brom in the race to sign Enrique.
The former Newcastle United full-back is a free agent after leaving Anfield at the end of last season, and has previously worked with Eagles boss Alan Pardew during his time on Tyneside.
As a result, reports suggest that Pardew is interested in a reunion with the Spanish defender, although it is understood that he faces competition from another former club West Ham, while former Palace boss Tony Pulis is also said to be keen on signing him at West Brom.
