Besiktas are chasing Chelsea striker Loic Remy.
The Turkish giants have lost star men Gokhan Tore and Mario Gomez this summer.
Sabah says they will push Chelsea for a season-long loan deal with an obligation to buy next summer.
Remy has two years left on the contract he signed at Stamford Bridge in 2014, following his £10.5m move from fellow west London side QPR.
