The Manchester United midfielder, who joined United from Spurs in 2006, also admitted that he had been surprised by just how big of an impact the Dutchman has had at Old Trafford.
"Robin will get stick from the Spurs fans, I'm sure, but he won't mind that and he'd love to score against them," he told The Sun.
"I don't think we expected him to come and score that many goals. It just seems that this was the right player to the right club at the right time.
"He's come here and settled straight in. He's been terrific."
United take on Spurs at White Hart Lane at 4pm this afternoon.
