The defender joined PSV on loan at the start of last season, helping it to win its first domestic Dutch title in six years.

The American made 37 appearances in all competitions, scoring two goals and adding seven assists.

PSV's loan deal for Dest included a future option to buy, with the Dutch side now choosing to trigger that, signing him on a free transfer that will keep him at the club until 2028.

"PSV believe in me and I feel greatly appreciated here," Dest said.

"I'm really looking forward to playing again, being important and winning titles."

Dest joined Barcelona from Ajax in 2020, making 51 league appearances in his first two seasons before loan spells at AC Milan in 2022-2023 and PSV thereafter.
