The bigger problem of Ajax is not just the coach that left, but the fact that they constantly sell off their star players. I know this is something they are known for since they have a very good academy but I think it's starting to catch up with them.
Since the season they had a very good Champions League run where they got to the semi-final, they've sold almost all their star players. Players like Frenkie, De Ligt, Shone, Tadic, Van De Beck, Neres, Blind, Antony and many more players have been sold.
Selling players when you don't have replacements is always a bad move. I believe they will get back with time because they also have a good recruiting team but they have to take this as a warning if they want to remain a relevant club in the league.
I agree with everything you said, Ajax are still not at the same good level they were in the past and in the game against Heerenveen they didn't lose only because Heerenveen's attacking players were not very inspired, Heerenveen players managed to make good passes, created good opportunities, but when it came to finishing they made mistakes, I believe that Robin van Persie needs to get better players to improve Heerenveen's attack, while Francesco Farioli will have a lot of work to do to improve Ajax and from what I see, this season Ajax only signed
Bertrand Traoré who comes from Villareal, and they brought
Christian Rasmussen from Ajax B, honestly I don't see Ajax being able to win the title, I see Ajax finishing in second or third place
After having worst end in last season we are having some development in Ajax even it's never been easy for team to have best quickly, but they are doing good and having good results with most chances in this season we will have them in UEFA Europa Cup because they are doing good at qualifying rounds and their start here in Eredivisie is also good even we can talk perfect but still this was good as they were able to beat Heerenveen by small margin as opponent also having new coach Robin Persie.
Ajax can go through for good results in this season while we are having usual all five teams at the top but as we have few changes of coaches and other we can expect some surprise because few clubs are looking for improvement and better end of their season in league table.
As an Ajax fan, I see that we will have another season of headaches:
We lost in a game where we had a good chance of winning. It's funny that
Ajax had 75% ball possession, had more shots on target and still only managed to score 1 goal and concede 2 goals against a not very strong opponent, so I predict that Ajax could end up in the same position they finished next season and I wonder:
when will we see Ajax fighting for the title? because I see that this season they are already showing signs that they are not ready to fight for the title, especially because PSV continues to be very strong as in the last 3 seasons. It is unbelievable how PSV has managed to maintain a good performance over the last 3 seasons and I see them being champions again this season.
result of the two great teams:
Heracles 1 - 3 PSV (PSV is starting the season very well, I see them becoming champions again)
Zwolle 1 - 5 Feyenoord (after a bad start to the season, in this second game Feyenoord crushed their opponent and are showing that they will compete with PSV for the title as they did last season)
