Palace trial duo
Palace have taken former Monaco striker Sebastien Grax and ex-Southend United winger Stuart O'Keefe on trial.
Eagles boss George Burley is looking to improve his attacking options and has offered Grax and O'Keefe the chance to earn deals at Selhurst Park.
Burley told the Croydon Advertiser: 'We are looking at every option available to us,We know we need more options, especially up front.'
Grax boosted his prospects by scoring for Palace's reserves in a 2-1 defeat by West Ham on Tuesday.
