Aston Villa have agreed a deal with Chelsea for left-back Ian Maatsen.

The fee for the 22-year-old is understood to be to be between £35m and £40m and it will rise with add-ons.

Maatsen will sign a six-year deal at Villa Park with personal terms not expected to be an issue.

Maatsen had a £35m release clause.

Borussia Dortmund were keen on signing the left-back on a permanent deal after his successful loan spell at the Bundesliga club last season.

He made 16 Bundesliga appearances for Dortmund, scoring two goals, and featured seven times for the German club in the Champions League, finding the net once.

However, as it stands, last season’s Champions League runners-up are unable to meet the release clause in Maatsen’s contract.

Sky Sports New chief reporter Kaveh Solhekol:

“Maatsen had a release clause in his contract, which Dortmund could have activated.

“That release clause has expired, which meant Aston Villa could make their move and that is exactly what they’ve done.

“It’s crucial that Villa are in the Champions League. The player himself wants to carry on playing in the Champions League.

“He’s expected to sign a six-year deal at Villa and it’s a very good deal for Unai Emery’s side.

“He played so well for Dortmund, helping them reach the Champions League final.”
