Since Erik ten Hag left Ajax, he caused Ajax to decline a lot and opened space for Feyenoord to start having real chances of winning the title, even in the case of PSV, they started to be a team that fights for the title after Erik ten Hag left Ajax, before Erik ten Hag became Ajax coach, Feyenoord had won the title when the coach was Giovanni van Bronckhorst. It's funny that PSV and Feyenoord in the last 8 years even when they change coaches, they continue to play well, while in the case of Ajax when coach Frank de Boer left the team fell for years, then Erik ten Hag came and recovered the team, but he left and the team declined a lot. The first rounds will determine whether Ajax has improved and whether PSV or Feyenoord will be title contenders again. The big 3 teams will have easier games in the first round. But in my opinion, if Feyenoord can play well throughout the next season like they did in this game against PSV, then they could be champions.
Change of coaches are normal thing for the clubs, but we need to check few things about Ajax as Erik ten Hag leave club we have few big players also follow him this was the turning point for club and Ajax suffer badly even they were into relegation zone for sometime as well, but now things are coming back to normal we are having good improvement into their performance so they are fighting hard for having spot into UEFA Europa Cup.
In last 14 years, we are having no winner other than Ajax 7 times PSV 4 times and Feyenoord 2 times, so Eredivisie is dominant by these clubs in near future I am having no changes because we are having no strength in any other club to challenge them for the title race just because of these things have never been entertaining here in this league.
