Although manager Redknapp had mentioned him to Levy over the summer, it was the Spurs supremo who made the move for the 27-year-old.
Such matters have been resigning matters for managers in the past but Redknapp is delighted with this particular instance of interference.
"Yeah, probably," he said. "He was on a list that we'd bandied about three months ago.
"I watched him play for Holland against Norway in Amsterdam and liked him.
"He's a good player and he'll link in with how we want to play."
