"For PSV it would be good if he stays, but for Strootman himself it's better to leave," Advocaat told De Telegraaf.
"He's the reserve captain of the Dutch national squad and PSV will make another step next season. This guy fits everywhere. He's a fantastic player because he knows exactly what his qualities are.
"Strootman is as good as Gareth Barry. He's a very useful player for every team. Especially when he's surrounded by better players."
