Feyenoord's perfect run in the Eredivisie ground to a shuddering halt at UtrechtFeyenoord's perfect run in the Eredivisie ground to a shuddering halt at Utrecht on Sunday.
Erwin Koeman's men have set a hot pace in the Eredivisie this term, but they found a Robin Nelisse-inspired Utrecht too tough.
Nelisse netted a hat-trick and his exploits ensured an own goal by team-mate Sander Keller was not too costly.
Ajax fought back from a goal down to claim a 2-1 win at Sparta.
Sjaak Polak fired Sparta in front on 52 minutes, but a brace of goals from Nigel de Jong secured a welcome three points for Danny Blind's men.
AZ Alkmaar joined Feyenoord at the head of affairs after a battling 3-2 win over NEC Nijmegen.
NEC matched AZ for long spells, but were undone by goals from Kenneth Perez, Tarik Sektioui and Shota Arveladze, having found the target themselves through Giulliano Grot and Andrzej Niedzielan.
PSV Eindhoven made ground on the leaders with victory at Heerenveen.
Former Manchester City man Paul Bosvelt fired Heerenveen ahead, but they had no answer to Arouna Kone who netted a second half hat-trick for PSV.
Niklas Tarvajarvi set up a grandstand finish with a goal on 89 minutes, but it failed to stop PSV claiming the spoils.
Two goals in as many minutes just before the break by Gijs Luirink and Yevgeny Levchenko handed Groningen victory over Willem II.
Twente secured their second win of the season, with Heracles put to the sword on Sunday.
All the damage was done after the interval, with Daniel Majstorovic, Kennedy Bakircioglu, Ramon Zomer and Blaise N'Kufo all finding the target.
