Wolves risk missing out on a huge cash windfall from any potential sale of in-demand defender Rayan Ait-Nouri due to a 50 percent sell-on clause in his contract.
Full-back Ait-Nouri has earned rave reviews for his displays so far this season and is attracting interest from across Europe with Paris Saint Germain and Barcelona among the clubs credited with an interest.
Premier League sides Liverpool, Manchester City and Tottenham are monitoring his progress.
But Wolves are facing a fight to keep hold of the exciting 20-year-old and they also face losing out financially on Ait-Nouri after his former club Angers inserted a 50 percent sell-on fee following his switch to Molineux last summer.
