The all-action 22-year-old wants to be a starter for both club and country in the coming years.
While he has typically played further forward in midfield, former Holland international Rafael van der Vaart believes he should play as a defensive midfielder.
I advise Ryan to opt for a role as a defensive midfielder," said Van der Vaart, speaking to Voetbal International.
That will not be an easy choice for him, because he can do much more. You can compare it with Nigel de Jong in the past.
Nigel could do much more than the subservient controller he eventually became. But in that specific role he reached an absolute top level.
Nigel decided he was going to be a pit bull and that's it. Ryan is also very versatile and I recommend him to make a similar choice. In a role like Patrick Vieira once played at Arsenal and France."
