I will play NED to win by nil/with a clean sheet +135 and put in a big bet on DEN Under 0.5 (same like NED clean sheet) +101.
Denmark can be tough to score upon, but NED not only features great individual players but is playing as a team: They circulate the ball really well and their transition game after forcing turnovers is extremely good. They also have very quick and skilled midfielders, who should cause trouble for the Danish defense, which is better suited for "big" physical opponents. In addition to that their offensive players have a great shooting technique, which shold also be a great asset with the new ball at this world cup, which already caused trouble several times for goalies. Free kicks are another plus for the Dutch, who have great free throw shooters with guys like Robben, Snijder, van Persie or van der Vaart.
Although I don't like the Dutch goalie and their defenders might not be the best individuals, they really improved defensively over the last couple of years, first and foremost by changing their coach: Since van Marwijk took over they are a much better team, especially when it comes to tactics and "spacing" the playing field, and their team defense improved much. Denmark also is a lowscoring team and imo will play extremely defensive minded, trying to shorten the playing field for the Dutch and more or less relying on counter attacks.
