Daily Mirror have reported that the player have struggled to make their mark during the loan spell and have not had considerable game time.
Therefore the Blues are willing to bring them back and loan them out to another club if need be.
The four players mentioned are Wallace, Chalobah, Feruz and Bamford.
Brazilian right back Wallace has failed to make his mark for Carpi and has made just one start for the Italian side. The young Brazilian is highly rated by many and will return to Stamford Bridge in January.
Furthermore, the talented central midfielder Nathaniel Chalobah is also set to return after failing to settle in at Napoli.
Patrick Bamford, the Championship player of the year in 2014 is also set to cut short his loan spell at Crystal Palace. The England striker has not been given a fair chance under Pardew and he could return to Middlesbrough on loan again.
