Feyenoord pretty much confirmed for their first league title in 16 years.
They don't have the greatest team, nor do they play the most attractive football, but they work hard and have been in the 1st spot of the league since matchday 1 so I guess it's deserved. They have been through rough times both financially and sportive (been just 7 years since that 10-0 vs PSV) recently so this league title is a nice symbol of their comeback as a club.
Ajax just came up short. It took some time for the players to get used to the playing style of the new coach Bosz but once they got going, they were and are playing really good and exciting football. The midfield of Schone, Klaassen and Ziyech is really strong, they signed a good centerback in Sanchez and they have a bunch of exciting prospects like Kluivert jr, Dolberg, de Ligt, van de Beek and many more. They just came up short for the league title but reached the semi final of the Europa League which is a big feat for a Dutch club these days. If they can keep the core of the squad together, which is never gonna happen, they are title favourites for next season for sure and might even advance through the CL qualifiers.
PSV absolutely fell apart this season. All of the players who were supposed to deliver (de Jong, Willems, Guardado) were dissapointing and the core of the squad is leaving in the summer too. Going to take a season or two of rebuilding to get back to competing for the title.
Also: Mastour was a total flop, Odegaard was anonymous /a flop too. Sam Larsson of Heerenveen is a nice talent for one of PSV/Ajax/Feyenoord. Dolberg, the Ajax striker, is a real one.
The worst days of the eredivisie in terms of quality seem to be behind us.
