Ajax have secured the 2021-22 Eredivisie title with a match to spare courtesy of a 5-0 success over Heerenveen on Wednesday night.
The Amsterdam giants entered the match knowing that a victory would see them land the trophy, with PSV Eindhoven, who beat NEC 3-2, four points behind.
Nicolas Tagliafico made the breakthrough in the 19th minute of the contest after smart work from Dusan Tadic, before Steven Berghuis doubled the home side's advantage in the 33rd minute.
Ajax then made sure of the points, and the title, in the 38th minute when Sebastian Haller converted from the penalty spot after a foul from Ibrahim Dresevic, before Brian Brobbey and Edson Alvarez both netted in the final exchanges.
The Amsterdam giants have now secured the Dutch title for the 36th time in their history, while it is Erik ten Hag's third Eredivisie trophy since taking charge of the club in December 2017.
Ajax, who have won 26, drawn four and lost three of their 33 league games this term, will finish their 2021-22 campaign against Vitesse on May 15, but Ten Hag's focus will now shift to the job that he is taking on at Manchester United this summer.
The Red Devils are currently battling West Ham United for sixth spot in the Premier League table, with their season finishing away to Crystal Palace on May 22.
The 20-time English champions confirmed on April 21 that Ten Hag had been appointed as their new head coach on an initial three-year deal, with the option to extend for a further 12 months.
"It is a great honour to be appointed manager of Manchester United and I am hugely excited by the challenge ahead. I know the history of this great club and the passion of the fans, and I am absolutely determined to develop a team capable of delivering the success they deserve," the 52-year-old said in a statement.
"It will be difficult to leave Ajax after these incredible years, and I can assure our fans of my complete commitment and focus on bringing this season to a successful conclusion before I move to Manchester United."
Man United suffered a 4-0 defeat at Brighton & Hove Albion last time out and will post their worst points tally in Premier League history this term regardless of what happens against Palace.
