Charlton Athletic are heading into a very important summer transfer window to improve on their disappointing 13th placed finish in League One.

The club's retained list was published on Tuesday afternoon, giving supporters and other clubs food for thought in terms of what areas in the squad will be addressed this summer.

The Addicks released Conor Washington and Jason Pearce along with a few other players who had been out of favour for an extended period of the season, while one-year extensions were triggered in the contracts of Nathan Harness, Josh Davison, Ryan Inniss and Jake Forster-Caskey.

Negotiations are ongoing with Ben Purrington regarding a new contract, with the Addicks looking very light in the left back position if an agreement is not reached with the 25-year-old.

The Addicks need to avoid leaving it until the final week in the window, as they did last season and made it more difficult to hit the ground running as a result.

Here, we have taken a look at eight free agents who would fit perfectly into Charlton Athletic's squad...

Tom James has enjoyed a very encouraging season at Leyton Orient with plenty of ups and downs, but the 26-year-old has been one of the best right backs in League Two.

The Cardiff City youth product has moved around a lot in the last few seasons following Yeovil Town's relegation from the fourth tier, but a player of his ability should be establishing themselves at League One level at this stage of their career.

The Welshman is a threat from dead ball situations and could help address the right back position at The Valley this summer.

Kane Wilson is the dream choice at right back, although the Addicks would face competition for his signature.

The 22-year-old won League Two's Player of the Season award and his deal with Forest Green Rovers runs out in the summer.

Wilson played in a right wing back berth under Rob Edwards this season and would add a degree of tactical flexibility for the, yet to be appointed, new manager at The Valley.

Wilson may have Championship offers but regular first team action should be his priority.

With left sided centre back Akin Famewo returning to Norwich City, the Addicks will need to bring in a player of similar profile, to avoid playing Sam Lavelle, Ryan Inniss or Deji Elerewe on their weaker left side next season.

Cheltenham Town's Will Boyle is the ideal candidate when his contract expires at the Jonny Rocks Stadium.

The 26-year-old is adept at bringing the ball out of defence and could complement Lavelle very nicely in building a foundation at the heart of defence next term.

Jack Tucker has gained a lot of League One experience, for his age, at Gillingham in the last few seasons and, due to their location, the Addicks are in a good position to sign him on a free this summer.

The 22-year-old is very strong in the air and will have other suitors this summer, Charlton were very inconsistent at the back this season and establishing some continuity from pre-season to the beginning of the campaign will be important if they are to improve next term.

Joe Powell has been a consistent performer in a defensive-minded Burton Albion side under Jimmy-Floyd Hasselbaink in the last two seasons.

The West Ham United academy graduate's contract runs out this summer and he will not be short of options.

The 23-year-old can play in a variety of attacking midfield roles and would add goals and assists to a side that was very reliant on Jayden Stockley and Conor Washington in 2021/22.

Powell's best position is as a number ten and his energy out of possession would make him a smart addition for the majority of third tier clubs this summer.

David Ajiboye has had a breakout season in the EFL with Sutton United.

The Amber and Chocolates have taken the fourth tier by storm and only missed out on the play-offs by one point.

Matt Gray's men also made the final of the Papa John's Trophy with Ajiboye an influential attacking cog off of the right flank.

The Brighton and Hove Albion academy graduate has a similar direct style to that of Corey Blackett-Taylor and would be an upgrade on Diallang Jaiyesimi at right wing.

The Addicks have linked up with Birmingham City on a number of occasions in the last year or so and they could further add to their attacking options by doing so this summer.

Powerful forward Jeremie Bela reaches the end of his deal at St Andrew's this summer and the Angolan has the potential to terrorise League One defences next season.

Bela has played at wing back this season but his strengths lie in attack, if the Addicks play a front three next season the 29-year-old would be a very exciting watch in the third tier.

Harry McKirdy has had a sensational season in League Two with Swindon Town, and rightfully made his way into the team of the season for his goals for the Robins.

The versatile forward has contributed 31 goal involvements this season and could yet have a huge say on the play-offs in the fourth tier.

At 25, McKirdy is a player on the up and would provide value in the transfer market to add some competition for places at The Valley next season, as per Transfermarkt his deal is up in the summer.
