Charlton Athletic have announced that assistant manager Johnnie Jackson has signed a new long-term deal at the club. 

A club legend that made nearly 300 appearances for the Addicks as a player, Jackson joined the coaching staff in 2017 and became caretaker assistant manager under Lee Bowyer in March 2018.

He helped Bowyer guide Charlton to promotion from League One last season.

The South London club have announced today that Jackson has signed a new contract that will keep him at the Valley until the summer of 2023.

Speaking to the Charlton website, the Addicks assistant boss revealed he has a "massive love for the club".

He added: "I’ve been here 10 years now, I feel like part of the furniture and I didn’t want that to end, so to get my future for the next few years secure and signed on is great.

“Hopefully we’re going to build on what we did last year. I think we put the building blocks in place then and now we want to try and continue that on this year, obviously by staying in the division and building from there.”

Executive chairman Matt Southall noted he was delighted that Jackson had signed a new deal at the club.

He added: "He’s absolutely integral to the club going forward and the work he and Lee have done together is the reason behind so much of the club’s success.”

East Street Investments completed their takeover of the club in January and it appears Southall is moving quickly to lock down the future of a number of key men.

Bowyer signed a three-year contract extension in January and Jackson has now signed a similar length deal.

Questions remain over the future of captain Lyle Taylor, who is out of contract in the summer, but it is understood the Addicks are keen to agree new deals with Naby Sarr, Dillon Phillips, and Alfie Doughty.

The Verdict

You have to admire the job that Southall has done since taking over as chairman.

He has moved quickly to secure the future of two key men in Bowyer and Jackson, and it appears we're likely to see some more deals completed before the end of the season.

Charlton sit 19th in the table, six points above the drop zone, and with the majority of their squad now fit, you'd back them to extend their stay in the Championship.

You feel Southall would become something of a hero to fans of the South London club if he can secure a deal for Taylor.
