Strange round in Eredivisie before international break. Ajax gamewith promoted Volendam ended 1:1. Didn't saw this game, but from stats it looks like equal teams played, Ajax didn't had advantage.
But even bigger upset happened in PSV - Telstar game. Champions lost game 0:2 at home against team that returned to top division after several decades. I guess that it can be biggest upset of whole season.
Twente also unexpected lost to Excelsior.
Tomorrow we will have Rotterdam derby between Sparta and Feyenoord.
