Chelsea legend, Geremi Njitap, says Ghanaian international, Baba Rahman, must prove his worth to break into Antonio Conte's set-up in the upcoming Premier League season.
Njitap, who played for Cameroun and Chelsea from 2003 to 2007, urged Rahman to work harder to break into the strong Chelsea team since that is the responsibility of every player.
Rahman joined Chelsea from German side, Augsburg, for £14 million in 2015 but failed to break into the first team after making just 15 appearances for the club.
