Burnley are furious over Bolton Wanderers' interest in manager Owen Coyle.
The Sunday Mirror says Burnley are poised to report Bolton to the Premier League for tapping-up Coyle.
Boss Coyle is close to informing the club that he wants to join their Lancashire rivals this week.
Under Premier League rules, it's illegal to approach a rival top- flight manager during the season unless the two clubs reach an amicable agreement and suitable compensation is agreed.
Bookmakers suspended betting on Coyle's appointment on Friday night after a flurry of bets sent his odds crashing.
Last night Bolton chairman Phil Gartside was hoping to open talks with his Burnley counterpart Barry Kilby.
