Spanish sports daily Marca reported that the 33-year-old Brazilian international is ready to sign for the Istanbul outfit in a transfer deal worth 5 million euros, ending his eight year association with Real.

Long regarded as the world's best left-sided full-back, Roberto Carlos had been linked with a move to Chelsea earlier this year but the prospects of a move to the English Premiership appear to have receded.

If Roberto Carlos leaves, Real will seek to replace him with Lyon's French international Eric Abidal, Marca added.
