Charlton Athletic’s five most expensive sales include a Europa League champion and Intertoto Cup winner.

Charlton Athletic are preparing for their first season back in the Championship after a six-year absence, this time in League One.

They earned their place back in the Championship by defeating Leyton Orient in the League One play-off final, which piqued the interest of their manager, Nathan Jones, who was later pursued by Cardiff City to become their new manager earlier this summer.

As the club prepares for life in the second tier alongside fellow League One departures Birmingham City and Wrexham, making a significant impact will necessitate astute transfer strategy.
