The Dutch ace made the most of Crouch's nod downs throughout the campaign.
"Crouchy is a great player," Van der Vaart told the Spurs website. "He is a big, tall guy but he can also play fantastic football.
"I remember in my first training session his heading ability was fantastic.
"He has a great technique, sees everything and when I played behind him it was easy to make goals.
"I think my first five or six goals were because he gave me the ball so he has been a really important player for me."
