The Dutchman impressed for Spurs after arriving in January from PSV, but a serious ankle injury derailed his season.
"I'm making progress," he told Spurs' official website . "As you can see, I can walk now and [I've got] my new boot, so that's good news.
"At the moment I got the kick [against Burnley] I thought it was serious. I was in so much pain and that night, I couldn't sleep. It was bad, but we're making progress and I'll come back stronger.
"I've had a good time here. I still have [despite the injury] – but these things happen. It's football."
