The 22-year-old has signed a five-year contract with PSV and will join the club for an undisclosed fee.
“I’m very glad to have signed for PSV and I’m really looking forward to wearing the shirt of PSV. I’m hopeful that I can make the next step in my career at this club,” said Lens on the club’s official website.
“It has been a very eventful season for me. However, the disappointment of missing out on Netherlands’ World Cup squad is gone after completing this deal.”
