Dutch agent Guido Albers says Vincent Janssen needs to leave AZ Alkmaar this summer.
The striker has been likened to Ruud van Nistelrooy and has been watched by Manchester United, Everton and PSV Eindhoven.
Albers, who takes care of Wesley Sneijder and Graziano Pellè, told AD: "What Vincent this summer must do is to make a transfer.
"He cannot have a better season with AZ than this one. New goals will help him."
Roger Linse, Janssen's agent, admits they're following the path of Van Nistelrooy:
"It'll be just like Ruud," he said, suggesting a move abroad will happen this summer.
