Maatsen is preparing for Netherlands' Round of 16 clash with Romania at UEFA Euro 2024 but will return to a new home at Villa Park for the upcoming 2024-2025 season.

The versatile full-back has reportedly signed a six-year contract with Villa after putting pen to paper on a move believed to be worth up to £37.5 million ($71.1 million).

Maatsen becomes Unai Emery's second signing of the transfer window after Villa brought in Lewis Dobbin from Everton earlier this month.

The 22-year-old spent the second half of last season on loan at Borussia Dortmund, reaching the UEFA Champions League final, which will provide useful experience as Villa prepares for a campaign including European football.

Maatsen managed 16 appearances in the Bundesliga and seven in the UEFA Champions League for Dortmund, scoring in a quarter-final triumph over Atletico Madrid.

The left-back made 15 appearances for the Blues after a successful loan spell with Burnley in the 2022-2023 campaign, but this move brings an end to his six-year relationship with Chelsea.
