Charlton Athletic defender Nathan Asiimwe has signed a new contract and joined AFC Wimbledon on a season-long loan.

The full-back, 20, has signed a two-year deal with the Championship club, who have an option to extend the contract by a further year.

He will spend the coming season with the newly-promoted League One side, managed by former Charlton player and boss Johnnie Jackson.

Asiimwe ended last season on loan at Walsall and was part of the Saddlers side pipped to promotion by the Dons in the League Two play-off final at Wembley.

He also had a spell on loan at Hartlepool United last season and has made 28 appearances so far for Charlton's first team since graduating from their academy.
