BURNLEY would be unlikely to let Kieran Trippier leave on the cheap, after it emerged the right back has a 40 per cent sell-on clause in his contract.

The Clarets were able to negotiate an affordable deal with Manchester City for the defender when he made his loan move from the Etihad permanent in January 2012, on the proviso that his old club would benefit from any future profit made on the former England Under 21 international.

Trippier cost Burnley around £450,000 when he signed a three-and-a-half year deal.

Trippier has attracted interest from Arsenal, Newcastle and more recently Stoke City but a formal bid has yet to be made to the Clarets.
