Ajax finished a remarkable title-winning season with a 14th consecutive Eredivisie win at Vitesse Arnhem.
The capital club needed late goals from retiring defender Andre Ooijer and Jan Vertonghen to secure the win.
Nicky Hofs had threatened to end Ajax's impressive run when he opened the scoring on 28 minutes, but a 41st-minute Dmitri Bulykin leveller paved the way for their late rally.
Vitesse had already wrapped up a Europa League play-off place but started stronger.
Jan Arie van der Heijden saw a second-minute shot touched onto the crossbar by Ajax goalkeeper Jasper Cillessen while Giorgi Chanturia shot just over.
Hofs should have opened the scoring on 23 minute but he tried to be too cute with his shot rather than blasting past Cillessen who was able to save.
Hofs made no mistake moments later, though.
The veteran attacker collected a pass from Chanturia and with a clever turn of foot broke into the area before finding the target.
Ajax were second best throughout the first-half but grabbed an equaliser just before the break through Bulykin. The striker had been anonymous in the game before ghosting in to head home a cross from Ismail Aissati.
After the break Vitesse hit the woodwork for a second time with Renato Ibarra this time denied before former Holland international Ooijer, playing his last ever game, grabbed a goal to sign off in style on 73 minutes.
The 37-year-old took a pass from Nicolas Lodeiro before beating Piet Velthuizen with a sweet finish.
Ajax then made the win secure on 80 minutes when Vertonghen, who himself was likely playing his last Ajax game with an expected move to England in the summer, smashed in a free-kick.
