"There's no problem whatsoever. Benni understands the situation and he'll be back very, very quickly and he'll have a major part to play this year," he told the Lancashire Evening Telegraph.
"We had a chat in the week and I just felt that Benni needed a little bit of one-to-one work, and when he has had that work his levels will be better.
"He is struggling with a little bit of form at the moment, he understands that, so once he's had the work we are going to put into him he'll be better for it, and he'll be able to have the impact he had last year.
"It's difficult to say (why his levels aren't where they should be).
"He had a bang early in the season and maybe that has affected him more than we thought.
"But I just felt as well, it was an opportunity to get Maceo Rigters on the bench.
"We had a good result in midweek (against Birmingham) and we felt it didn't warrant too many changes, and I think it just illustrated the strength of my squad."
