To my mind sadly Nizzy is the one to miss out though he is deserving of a spot...
For me Nizzy has amazing skills and is progressing rapidly. His strengths are dribbling and tenacity. His obvious weakness is his lack of size.
So, while he is not a great interceptor of the high ball or has the mass to push big attackers off the ball (so cannot match Olli, Stenz or Jano...) he is brilliant at working in tight spaces.
I do think he would be best suited to a number 10 role than a defensive midfielder position. In a 4231 he would be the man for the centre of the 3.
I think in the current 442 he needs to be on a wing with freedom to come in and create havoc behind the strikers.
