I have written about NEC's playing style and their coach several times; I won't repeat myself. You can read about it here:

AFC, on the other hand, is a semi-pro team with a big tradition as they are the oldest team in Amsterdam, a lot of oldskool Ajax heads have a bond with AFC. They play in the Tweede divisie, the same division as Rijnburgse Boys. Rijnsburgse Boys scored twice against NEC in the previous round, making life difficult for NEC. AFC has some interesting players, such as former Ajax player van Rhijn (former Dutch international as well), and also Melvin Platje (former NEC).
NEC has a very deep team, played with a lot of reserve players against Rijnsburg Boys, pretty much a team that has a better bench than teams like Feyenoord or Twente. They could score 3-4 goals all by themselves. At the same time, I won't be surprised if AFC scores a goal or two.
Hence, play goals.
