It all seemed and decided race. Ajax was doing very well in the Champions League and PSV has not even qualified for the CL. We now see that PSV has taken over and it is not so clear anymore. We should also take Feyenoord into account. Ajax is the favorite for the title, but PSV is closer than originally thought. If you become champion with that selection of Ajax, then that is a failure. The budget of Ajax is almost more than the rest of the Eredivisie put together. It is actually the Bayern Munich of the Netherlands, only they have a very bad start and Ajax a reasonable one. I also expect a few things from Twente.
Competition in the Eredivisie is only about PSV and Ajax, even so, Ajax appear to dominate in the league in general, it can be seen from the last 4 seasons that only they have won the league there.
Referring to the current Eredivisie standings, the points from Ajax and PSV are 18 points, it's still early in the league, maybe we will see which team will win the league after half of the game has been running. I think, Ajax will be the winner of the league title for the 5th time in a row.
About Twente, we can't expect much from them, season after season they are just a middle-class team that won't be able to win the league.
