Billy Koumetio leaves Dundee for Charlton Athletic
Billy Koumetio has left Dundee to join Charlton Athletic for an undisclosed fee, the club confirmed on July 1, 2026. The defender ends a two-year spell at Dens Park after 43 competitive appearances and heads back to English football following his August 2024 move from Liverpool. The transfer is one of the headline Scottish exits as the summer window reshapes squads across the Premiership.
Dundee Football Club announced the deal in an official statement, confirming Koumetio's move to Charlton Athletic is complete. The news lands during a busy period at Dens Park, with Scotland Under-21 centre-back Luke Graham also set to exit after Dundee agreed a deal worth around £2 million with Stoke City, according to The Scotsman.

What did Billy Koumetio achieve at Dundee?
Koumetio arrived from Liverpool in August 2024 and made his debut the following day, coming off the bench in a home league win over Heart of Midlothian. He went on to feature in 43 competitive games, described by the club as a consistent part of the defence throughout his two seasons as a Dee.
His only competitive goal came in the League Cup group stages against Bonnyrigg Rose in July 2025. That record underlines the role he played at the back before Charlton completed his signing.

Charlton Athletic are Koumetio's destination, marking a return to English football after his Scottish Premiership stint. The fee remains undisclosed, but the move places him at Charlton ahead of the new season.
