Wolverhampton Wanderers have reportedly been quoted a fee of around £10.7m for the permanent signing of Porto defender Willy Boly.
The 26-year-old has impressed for Wolves since joining on loan in the summer, his 16 appearances yielding 10 clean sheets for the Championship leaders.
Boly cost Porto €6.5m (£5.8m) from Braga in the summer of 2016, but has made just five appearances in all competitions for the Portuguese giants.
According to O Jogo, the defender's parent club has quoted Wolves €12m should the West Midlanders wish to recruit the Frenchman on a permanent basis.
Wolves are eight points clear of second-placed Bristol City, whom they visit on Saturday.
