Aston Villa have agreed a deal with Chelsea to sign Dutch defender Ian Maatsen.
The 22-year-old will cost between £35m and £40m, depending on potential add-ons, and the move is subject to a medical as the left-back is expected to sign a six-year deal at Villa Park.
Maatsen opted for Villa due to the promise of Champions League football next season, having reached the final of the competition while on loan at Borussia Dortmund during the second half of last season.
The Blues had discussed signing Villa striker Jhon Duran as part of a swap deal but have opted to sell Maatsen in isolation.
