Chelsea defensive duo John Terry and Branislav Ivanovic have struggled this season as a result of their uncertain futures, according to a report.
Both players have endured shaky starts to the campaign as the Premier League champions sit 17th after losing three of their first five domestic games.
The pair were dropped for the Blues' 4-0 Champions League win over Maccabi Tel Aviv and it remains to be seen whether or not they will be recalled for Saturday's visit of Arsenal.
Captain Terry and Ivanovic are out of contract next summer and, according to The Mirror, that instability has done nothing to help their early-season form.
The report goes on to claim that Fenerbahce are interested in signing the duo, who will both be free to negotiate with foreign clubs from January 1, unless their situations are resolved.
It has been Chelsea's worst start to a league season for 29 years.
