PSV which is having third defeat of this season while they have first lost in Eredivisie after lost against Nijmegen in March surely start feeling pressure because this defeat is surely mean for them, and they needed to be had improvement into their performance if they want to stay at the top.
Ajax is dangerous side which can now bring some good power for having challenging position in title race as we have surprise package Utrecht with 22 points and 2 games in hand third title contender in this current season after ended last two seasons on 7th spot while Feyenoord, AZ Alkmaar and Twente are struggling for bringing themselves into good position in this season.
Yes and if this game ended differently, you could have almost ended the season in the Netherlands and call PSV the new champion. It would have been 11 points if PSV won that game and they have the overwhelming better goal difference. So for those following that league this was good news because it keeps at least some little excitement alive. But then again I doubt that PSV will fall behind ever this season because of this game. At the end of the day they can most likely easily afford a loss like this as there are barely teams who can really become a threat to them. But for Ajax this was good news to finally see that they can compete with them.
