Bolton Wanderers aren't expected to cough up much more for the signing of ex-Wolves academy prospect Mark Connolly.
Wolves have lodged a formal complaint with the Premier League and the FA over the manner of the 17-year-old's departure to Bolton on transfer deadline day last month.
But The Times says if the dispute cannot be settled, it could go to an independent tribunal appointed by the Premier League. It is thought that Wolves would struggle to extricate any further fee from Bolton, having been well compensated at the time of agreeing the deal in August.
