Sordell blossomed under Dyche's watch at Watford, first as a youth team player before progressing to become a £3million-plus signing for Owen Coyle's Bolton in January 2012 on the strength of scoring 25 goals in a season-and-a-half at Vicarage Road.
"He has had a tough couple of years over at Bolton after going there for a big fee, but he's a young man and when you have an awkward time that can teach you as much as anything about yourself," he said. "It's just about giving him that freedom to express himself as a young footballer.
"There is talent there and that's important and I think he knows that it is a good chance for him to re-invent or add to what he is."
