Kairat Almaty suffered their first league defeat since May 2017, losing 1-0 to relentless Tobol Kostanay on the road.
The 30-game streak without a loss built by Kairat across the last 12 months came to an end after their visit to dogged Tobol side.
A late goal from Tanat Nuserbayev handed Carlos Alos Ferrer his first defeat since his appointment as Kairat manager in summer 2017.
With Andrey Arshavin on the bench for more than an hour of football in Kostanay, Kairat lacked ideas against well-organised opponents.
But things changed little when the former Arsenal FC man entered the tight game in which goalscoring chances were at a premium.
Nevertheless, Tobol looked more dynamic and focused of the two sides, especially in the final third of the match.
In the 64th minute, Fernander Kassaï headed the ball against the crossbar before Viktor Dmitrenko's header was ruled out for offside.
Tobol's approach paid off late on, with substitute striker Tanat Nuserbayev hitting the winner one minute from regular time.
Kairat defender Aibol Abiken missed a brilliant chance to open the scoring, directing his point-blank header straight into the gloves of Dmytro Nepohodov.
The hosts responded instantly moments later through a counter as Nika Kvekveskiri slalomed down the left before teeing up Nuserbayev at the far post for an easy finish.
Kairat remain second in the league though their deficit on the pacesetters FC Astana increased to five points though Alos' men have a game in hand.
Vladimir Nikitenko's charges, on the other hand, moved to provisional third place, closing the gap on Kairat to four points.
