Charlton Athletic made their return to the Championship after winning the League One playoffs last year and they made a number of new signings over the summer in their bid to stay up. However, the Addicks are in a relegation dogfight and will be looking to bolster their squad in the January transfer window. Nathan Jones's side have made some key signings, including Harry Clarke on loan from Ipswich Town and Lyndon Dykes from Birmingham City. The club have also brought in Zach Mitchell on loan return from Hibernian, Luke Chambers on loan from Liverpool, and Tiernan Brooks from Gateshead. Charlton Athletic have also signed Jayden Fevrier on loan from Stockport County, Conor Coady on loan from Wrexham, and Collins Sichenje from FK Vojvodina. The Addicks have let go of Jerome Roussillon to Amiens, Rob Apter on loan to Bolton Wanderers, Tanto Olaofe on loan to Stockport County, Ashley Maynard-Brewer to Dundee United, and Karoy Anderson on loan to Blackpool. The January transfer window opened on Thursday, January 1, and will run through to the first weekday of February, with the deadline day falling on Monday, February 2, at 7pm GMT. Charlton Athletic's total spend in the January transfer window is £0m, with a total income of £0m, resulting in a net spend of £0m. The club will be looking to use the remainder of the transfer window to further strengthen their squad and boost their chances of survival in the Championship. With the signings they have made so far, Charlton Athletic will be hoping to climb out of the relegation zone and secure their place in the Championship for next season. The Addicks have a tough task ahead of them, but with the right signings and a bit of luck, they can turn their season around. Charlton Athletic's fans will be eagerly waiting to see how the rest of the transfer window unfolds and how their team will perform in the remaining matches of the season.
