List of matches in which Ajax lost big (at least 3 goal difference), while Ajax still became champion.
The large number of appearances of Feyenoord on this list is partly explained by the fact that throughout the years Feyenoord was often the strongest opponent Ajax faced, but also supports the generally accepted rule that matches between Ajax and Feyenoord were stand alone in the sense that they typically did not reflect the difference in strength one could expect based on the competition standings.
