Crystal 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.
In addition to Monaco, Grax has also played for Guingamp, Troyes, Sochaux and St Etienne, while O'Keefe left Southend over the summer.
"We are looking at every option available to us," said Burley in the Croydon Advertiser. "We know we need more options, especially up front."
Grax boosted his prospects of being offered a contract by scoring for Palace's reserves in a 2-1 defeat by West Ham on Tuesday.
