Ajax set a new Eredivisie record by thrashing 10-man VVV-Venlo 13-0 on Saturday.
Lassina Traore scored five goals as Ajax shrugged off their midweek Champions League defeat by Liverpool to move back top of the table.
Jurgen Ekkelenkamp opened the scoring after 13 minutes before Traore hit a double and Dusan Tadic made it 4-0 at half-time.
The home side saw defender Christian Kum shown a straight red card six minutes into the second half, with Ajax then scoring an incredible nine more goals.
Traore completed his hat-trick in the 54th minute, capitalising on a mistake by beleaguered Venlo goalkeeper Delano van Crooij, with Brazilian forward Antony adding a sixth.
Ekkelenkamp got his second and then Daley Blind scored the eighth on the hour, with Traore making it 9-0 before substitute Klaas-Jan Huntelaar scored twice in the space of two minutes, one from a penalty.
The Amsterdam side soon had a 12th through Lisandro Martinez’s long-range effort before Traore completed the rout with three minutes left.
Ajax’s tally bettered their own previous record 12-1 victory over Vitesse in May 1972, and sent them back to the top of the table above PSV Eindhoven.
