Udinese midfielder Emmanuel Agyemang-Badu says Abdul Baba Rahman will improve next season at Chelsea.
The 21-year-old has struggled to make an impact at Stamford Bridge since joining from Augsburg during last summer's transfer window.
But Agyemang-Badu believes new manager Antonio Conte will help the youngster improve.
"Baba Rahman will perform 120 per cent well under Antonio Conte [at Chelsea] next season," Agyemang-Badu told Starr FM.
"This time he will join Chelsea for pre-season, something he did not get last season. So I am sure he will do very well under the new coach."
Rahman joined Chelsea for an undisclosed fee last year after agreeing a five-year contract with the club.
