I would be lying if I said I wasn't shocked by Feyenoord's loss to PSV since Feyenoord has been playing well this season and PSV lost their last away game to Heerenveen by a single goal. Because it is a derby match, I believed that PSV would struggle against Feyenoord after seeing the result of their match against Heerenveen. PSV scored three goals to control the game from start to finish. I believe PSV will still win the Eredivisie at the end of the season.
PSV played very well but on the other hand Ajax also followed with quite impressive improvement, PSV victory with 3 goal against Feneyord was great success, some people considered it difficult match for PSV to win but in fact they win.
Just saw the standings and PSV so far for half season has 15 win with total of 59 goal and only conceded 13 goal, they have many wins with more than 3 goal obtained and PSV is still the only team with the most sharp and dangerous front line players, it seems that what you said is true that PSV will remain win title in the Eredivisie this season.
Now we have 2 weeks left in break things could be interesting because now we have Ajax in better shape, and they are capable of giving challenge to PSV for the title race with attacking approach is different, but this could be good time for fans to watch how these two big giants of Eredivisie go for second half of this season.
Feyenoord is challenge for both teams with third spot race could be also good because we have AZ Alkmaar and Utrecht could be not easy opponent for the Feyenoord as these are also having good time and looking for improvement into their European competitions, but top race is surely still alive as PSV and Ajax are going to be had good time even mostly are believed PSV is having advantage but in European Leagues 6 points are never been big difference.
