Moses, 28, underwent a medical on Thursday ahead of a switch to Turkish club Fenerbahce.
The former Nigeria international is expected to sign a deal until the end of the season.
He was a first-team regular prior to the arrival of Maurizio Sarri as Chelsea boss but has made just five appearances this season.
Moses has started just one game this term – the Carabao Cup win against Liverpool in September.
