Aston Villa sign Dutch defender Maatsen from Chelsea for reported £37.5 mn
No fee was disclosed, but several British media outlets reported Maatsen had moved to Villa in a deal worth £37.5 million ($47.4 million, 44.3 million euros).
The 22-year-old left-back was a member of the Borussia Dortmund team beaten 2-0 by Real Madrid in the Champions League final at Wembley earlier this month while on loan from Stamford Bridge.
He is currently with the Netherlands at Euro 2024 in Germany after being called into the squad as a replacement for injured Barcelona star Frenkie de Jong.
Maatsen is the second player signed by Villa manager Unai Emery in the pre-season transfer window following forward Lewis Dobbin's arrival from Everton.
Villa are now preparing for Champions League football after finishing fourth in the Premier League last season.
Maatsen made 16 appearances in the Bundesliga and seven in the Champions League for Dortmund, including scoring in the German club's European quarter-final win over Atletico Madrid.
He also featured in 12 Premier League games for Chelsea last term, having previously been loaned to a trio of English clubs in Charlton, Coventry and Burnley.
