Tottenham boss AVB: Van der Vaart must stay
Villas-Boas maintains Holland midfielder Van der Vaart is an integral part of his plans.
"With Van der Vaart, at the moment I am absolutely counting on him," he said.
"It is a totally different situation from Luka, who has been chased by different clubs in the past two seasons and is continuing to drag interest.
"We have to make sure the club's interests are met, and it is up to the chairman to decide that."
