Charlton Athletic are ready to make a move for former Peterborough United attacker Marcus Maddison, Football Insider can exclusively reveal.

The Addicks tried to sign the 27-year-old in January of this year before he completed a loan move to Hull City.

A recruitment source has told Football Insider that Charlton are readying an offer for the attacking-midfielder that is available on a free transfer.

Maddison is a free agent this summer after he left Peterborough United upon the expiration of his contract in July.

Former Sunderland and West Brom striker Kevin Phillips is adamant that the left-footer would be “an asset” to a League One club if signed.

His 33 appearances for the Posh last season yielded an impressive 11 goals and eight assists as the club narrowly missed out on the play-off spots after League One was curtailed.

Football Insider revealed last month that Derby County had set their sights on signing the playmaker with MLS outfit FC Cincinnati and Belgian side Zulte Waregem also keen on a deal.

The Newcastle United academy product was a standout performer in his six-year stay at Peterborough, with 154 goals involvements in 249 appearances.

Maddison has been very open on social media about his search for a new club and has recently trained with Peterborough Sports FC who play in the Southern League Premier Central division.

Charlton boss Lee Bowyer has already strengthened his squad with the signings of Alex Gilbey, Ben Watson, Conor Washington, Dylan Levitt and Akin Famewo following their relegation from the Championship last season.

The Addicks have suffered an indifferent start to the season with an opening day win at Crewe Alexandra followed by disappointing losses against Doncaster and Lincoln City.
