Charlton Athletic have confirmed Lee Bowyer is set to leave the club imminently.

The 44-year-old has resigned from his post as manager at the club.

Bowyer is set to take over at Birmingham City, who have parted company with Aitor Karanka.

He told Charlton's official website: "It was a difficult decision to leave. Everyone knows how I feel about the club. I could have gone before, but I felt it was the right thing to do to stay and help the club through the tough times we've been through.

"We had some amazing times and some tough times. It has been emotional leaving. I'd like to thank all the players that I've worked with and the staff for the hours and hours of hard work that they did. I also want to thank the supporters. We wouldn't have had those great memories without them.

"The club is now in a place with a good owner that cares and wants to improve the place and I hope the club can continue to grow. It will always hold a special place in my heart."

Club owner Thomas Sandgaard, who bought Charlton in September, said: "I would like to thank Lee for everything he has done for Charlton. I have enjoyed working with him and wish him the best for his future. Our focus now is on finding the correct replacement to take this club forward."
