Portsmouth boss Paul Hart is expecting more from Aruna Dindane after his hat-trick against Wigan last week.
The Lens loanee had failed to score in four league appearances prior to last Saturday's 4-0 win over Wigan at Fratton Park.
But Dindane answered his critics with a stunning hat-trick and Hart hopes to see more of the same at Ewood Park.
He said: "I think that's what he has been missing. He's very hard on himself and he felt that he should have scored before then.
"Now he has to maintain that form, but apart from scoring goals, his performances have been excellent.
"He has managed his frustrations and got on with his job. It's like all centre forwards, they want to score.
"But I was telling him that he was getting there to miss them and that if he continued to do that, it would come."
