The Portugal international was brought to Stamford Bridge by former boss Andre Villas-Boas and since his countryman was shown the door the playmaker has struggled to hold down a consistent place in the side.
With a number of new midfielders being signed by the Champions League winners this summer, Meireles has been deemed surplus to requirements and has moved to the Turkish giants.
“Raul Meireles has today joined Fenerbahce on a permanent transfer. The move was completed before the close of the Turkish transfer window later this week,” a statement on the west London club’s official website reads.
Meireles had only started one of the Blues’ three Premier League games this season so far, and was an unused substitute for their 4-1 defeat to Atletico Madrid on Friday night in the European Super Cup.
