Crystal Palace are seeking a deal for Olympique Marseille striker Iliman Ndiaye.
The former Sheffield United star is available from OM this month after battling for minutes since his August arrival.
A return to Bramall Lane has been mooted, with West Ham also keen.
And The Sun says Palace are making a move as they seek to boost their attack.
The concern for Palace is that Ndiaye is currently in Ivory Coast with Senegal for AFCON, so making negotiations complicated.
