Jones was plucked out of the League One wilderness by the former head-coach and ex-sporting and technical director Dan Ashworth, and now looks a real steal.
"Roy was massive for me," said the 26-year-old to the Sunday Mercury.
"To Roy and Dan Ashworth - the main people involved in that move - I have to say thank-you.
"I'd just been playing at Preston, a team that had been relegated from the Championship to League One.
"They saw enough to give me the chance of playing Premier League football.
"It was crazy. It therefore turned out to be a good season for me, even though we got relegated."
