Sources: Bowyer quits Charlton and lined up to take over Birmingham City

Lee Bowyer has resigned as Charlton Athletic manager and been lined up to take over at Birmingham City, Football Insider can reveal.

The 44-year-old left the Addicks at lunchtime on Monday and a formal statement is being prepared.

A Charlton source has told Football Insider that the club believe Bowyer is wanted by Birmingham to replace Aitor Karanka.

The Spaniard was sacked on Sunday after the Championship club were beaten at home 3-0 by Bristol City 24 hours earlier.

He leaves the Blues just three points above the relegation zone with 10 games remaining in the Championship.

Bowyer has been in charge of Charlton for three years after initially taking over as caretaker manager in March 2018.

He steered the club to the League One play-off semi-final and was then handed the job permanently.

Bowyer oversaw promotion to the Championship in his first full campaign, although Charlton were then relegated 12 months later.

The Londoners are in contention for promotion again this term and Bowyer leaves with them eighth in the table and two points off sixth-placed Ipswich Town.

By contrast, Birmingham are battling to avoid relegation.

The West Midlands side have won just two of their last 12 league fixtures, one of which was a 1-0 victory over a Sheffield Wednesday side reduced to 10-men.

Birmingham have a torrid run of fixtures over the next six weeks and face four of the Championship’s top-five sides.

They are 21st in the table, one place and three points above the relegation places.
