Reports say Kean has told Diouf to reform the ‘nasty’ side of his character after the fiasco the club had after the game with Queens Park Rangers in the FA Cup.
Diouf was accused of taunting QPR striker Jamie Mackie as he lay on the ground with a broken leg during their FA Cup tie at Ewood Park.
Agent Willie McKay said: "El-Hadji is looking to make a fresh start. He is a good player and there is plenty of interest."
