Peterborough United have put star midfielder Marcus Maddison on the transfer list following the conclusion of the 2017/18 campaign.
The 24-year-old has contributed 12 goals and 23 assists in 52 games in all competitions this season, with Posh missing out on the play-offs.
Maddison has formed a fantastic partnership with striker Jack Marriott, who picked up the Sky Bet League One Golden Boot.
Nottingham Forest have been linked with a move in recent months, whilst Leeds United are also believed to be interested.
Speaking to Peterborough's club website, chairman Darragh MacAnthony said: “When I sat down with Marcus last August and agreed a new contract with him, I gave him my verbal assurances that were we to fall short and not gain promotion, I would allow him to leave the club subject to an offer acceptable to the football club and place him on the transfer list.
“Marcus has been in his four years with the football club our stand out attacking midfielder and one of the best players offensively outside of the Premier League and the Championship.
"He has had an incredible career with the Posh and it is only right that I stick to my word and give him the best chance possible to further his ambitions of playing further up the football pyramid so with sadness today (Thursday), I can confirm he is available for transfer."
Maddison joined Posh from non-league outfit Gateshead in August 2014 for an undisclosed fee and announced his arrival by scoring on his home debut against Leyton Orient.
He was renowned for his finishing in dead-ball situations and won Peterborough’s Goal of the Season for his stunning strike against Shrewsbury Town last season - an effort that was in the final five at the EFL’s end of season awards.
