Well if Ajax wins against FC Utrecht they can win the championship in the match against AZ so they will take that much seriously. No way they dont take that match not that serious. They have plenty of time to win the championship but the sooner the better.
if there is a chance to win a championship at home, than Ajax will try to use it, although there is no fans on the stadiums, and will be creepy to celebrate on an empty stadium
nevertheless, it does seem that Ajax would like to take the championship as soon as possible, they are in winning strike, now without Europa league disturbance, and that leaves AZ with lower chances to avoid lose in Amsterdam
