As bad as the series against AZ is in recent years, the series in the Eredivisie after European duels is so good. The Amsterdammers have already played twelve matches after European obligations this season. Ajax won ten times, played a draw once and only lost once (in August against NAC Breda).
AZ has a lot more difficult this season after European competitions. For example, four times, but also lost so often (of which three times in a row in -house). The Alkmaarders once took a point.
