Jonson Clarke-Harris could be worth as much as £2 million plus add-ons, according to the owner of one of his former sides.
Sheffield Wednesday are among the Championship clubs who have had Clarke-Harris watched this season, Bristol Live claims.
Another of those, Hull City, are said to have been unwilling to spend more than £450,000 on the Bristol Rovers striker following an enquiry.

And Darragh MacAnthony, who had Clarke-Harris at Peterborough United earlier in the 25-year-old’s career, believes that figure is well below his true valuation.
Asked how much interested clubs should expect to pay for Clarke-Harris in January, the Irishman replied:
Clarke-Harris is the latest centre-forward to be linked with a move to Wednesday ahead of the winter window, after Lyle Taylor and Rhian Brewster.
The former Rotherham United and Doncaster Rovers striker has scored 21 goals in 33 games since being brought to Bristol Rovers at the start of the year by the former Owls defender Graham Coughlan, who quit to take charge of Mansfield Town last week.
