Chelsea are prepared to sign Saul Niguez on a permanent deal if he impresses during his second-long loan move.
The Spaniard joined the Blues from Atletico Madrid on loan on deadline day. The club have the option to buy him for €40m.
Saul had a dreadful debut against Aston Villa on Saturday as he was guilty of losing possession on numerous occasions.
Thomas Tuchel personally was not pleased with his efforts, and he substituted him at the half-time interval for Jorginho.
Despite the poor showing, there are reports suggesting that the Blues are open to triggering the buy clause next summer.
Rice has been linked with a return to the club for several years, but a deal has not materialised with only speculation in the media.
The England international could still leave the Hammers next summer. Manchester United are lining up a potential bid.
