This is how I would play with Ajax on attack. It is more or less how van 't Schip made them play in the first games formation wise. A sort of 3-2-4-1 with a square on midfield. You need at least 1 defence minded player on the winger which could either be Sosa or Gaaei (maybe even both)

This is how it would look on Defense: https://sofifa.com/squad/1699720
