Diouf has vowed to not celebrate if he scores against them on Sunday but score is exactly what he will be trying to do.
"I've got a great relationship with the Trotters fans and I really don't want them to go down," he said in The Sun
"But my job now is to win the match for Blackburn, as we still feel we can make next season's Europa League.
"If I can score on Sunday I will not be celebrating it like I normally do - but I do want three points for my current club.
"Even though I have a good relationship with Bolton, I will take the opportunity to score if I can."
