The Turkish side are determined to add a creative midfielder to their squad and have marked the Spain and Brazil internationals as potential signings in January
Real Madrid midfielder Isco and Chelsea's Oscar have emerged as loan targets for Turkish Super Lig side Fenerbahce, according to Sporx.
Fener are looking to use the playmakers' lack of game time at their respective clubs to their advantage and are keen to take one of them on loan until the end of the season.
Isco has made seven starts for Zinedine Zidane's side this season, scoring twice, and just once in the Champions League, and is expected to leave the Spanish capital on a permanent basis in the summer.
