Peterborough United chairman Barry Fry has told the Peterborough Telegraph his side will only sanction a deal for Marcus Maddison which matches his release clause.
According to TEAMtalk, Derby County, Middlesbrough and Blackburn Roves are among several Championship clubs looking at a potential deal for the player.
Maddison’s contract at Peterborough expires next summer. Moreover, he has a well-documented release clause of £2.5 million which the League One club must abide by.

But Posh chairman Barry Fry has warned the likes of reported suitors Derby, Blackburn and Boro that his side won’t accept anything less – even a bid of £2 million.
Marcus is different as if a club meets his transfer clause we can’t stop him leaving, but we will reject any other bid, even one as big as £2 million. The main intention for January is to sign players.

Maddison represents a potential bargain at £2.5 million, despite his contract situation.
The 26-year-old has shown he is clearly a level above League One standard. In 15 league starts, he has an impressive nine goals and six assists.
Maddison can play either as a number 10 or in a wide role. He is clever on the ball, creative and looks to get shots off. He is comparable to Hull City’s Jarred Bowen in that regard.
Derby, Blackburn and Boro have all struggled for goals this season. The latter in particular have managed just 13 goals in 16 league games as they sit in the bottom three.

While some point to the strikers, a lack of creativity is arguably the three club’s biggest issue this season. Maddison would no doubt have a positive impact at either club.
