Clarke-Harris only joined Posh last summer, but has performed goalscoring heroics at London Road this season to put Peterborough on course to end their eight-year wait to return to the Championship.
The former Bristol Rovers man has scored seven goals in his last seven, taking his total to the campaign for 29 in League One, four ahead of his closest rival, Charlie Wyke, in the race for the Golden Boot.
Clarke-Harris has previously played in the Championship with Rotherham, and Fry confirmed that four second-tier sides tried to sign the Posh striker in January.
But with Peterborough well-placed in the thick of a promotion race, they rejected all offers, although recent reports believe that the 26-year-old could be lined up as a replacement for Alfredo Morelos at Rangers, with recently relegated Sheffield United also keen.
Peterborough’s Director of Football told Football FanCast:
“He’s got 29 goals this year. He’s been magnificent leading the line, and he’s done exactly what we thought he would do and long may it continue.
“There was a lot of interest in him in January, four clubs in the Championship came in for him, but we turned them all down. You don’t sell your best players in January if you want to go up. There will be further interest in the summer, depending on what league we are, but we will get a lot of offers.
“He deserves to be at a bigger club and if he was at a bigger club he would score the goals he scored this year because he’s a goalscorer.”
