The former Swansea City star believes Pratley can replicate that kind of form at a higher level after his arrival at the Reebok.
"I left Swansea about the same time as he came in from Fulham but I go back regularly to watch games and speak to a lot of players who were there," he told the Bolton News.
"People say he's a good professional and you can tell from watching him play that he's got good energy and an eye for goal.
"It's a step up to Premier League level but I think he'll handle it. The gaffer will have done his homework and I'm sure he'll be a good signing for us."
