Lokomotiv Moscow moved to the brink of qualification for the Europa League knockout stage with a one-sided 3-1 win over pointless AEK Athens.
Denis Glushakov's opener was cancelled out by Leonardo's penalty but Lokomotiv hit back, Maicon and Vladislav Ignatiev securing a deserved three points.
The win leaves Lokomotiv six points clear of next opponents Sturm Graz with two games remaining and they look sure to follow group leaders Anderlecht into the last 32.
Lokomotiv dominated the early exchanges, with Senijad Ibricic and Victor Obinna threatening with 20-yard efforts.
Glushakov's drive was blocked before Roman Shishkin swung the ball goalwards from 30 yards out on the right wing and keeper Giannis Arampatzis punched clear.
Grigoris Makos ensured visiting keeper Guilherme was involved with a 30-yard left-footed effort, but it was a brief cameo by the Greek side's attack.
Dmitriy Torbinsky fired wide of the near post and Shishkin's long-range effort was held by Arampatzis.
The visitors were desperate for the goal their total dominance merited and had a flurry of shots as half-time approached, Ignatiev shooting wide before Alberto Zapater's long-range drive flew over.
Ignatiev saw an effort blocked by Kostas Manolas and then dragged another shot wide as the half somehow ended all square.
But the Russians finally broke through five minutes into the second half, Glushakov turning home Obinna's cross.
That woke the home side up and Jan Durica had to be alert to block Jose Carlos' 20-yard shot.
The same player then drew a sharp save from Guilherme before AEK improbably levelled, Leonardo scoring from the penalty spot having been fouled by Shishkin.
Jose Carlos shot over but AEK's good spell came to an end when Arampatzis' calamitous error allowed Lokomotiv to restore their lead. The keeper attempted to dribble round Maicon on the edge of the box but gifted possession to the substitute, who finished with ease.
The home defence was culpable once more as Ignatiev made it 3-1 with 10 minutes remaining, the midfielder seizing on a poor clearance and firing home.
Glushakov and Obinna tried their luck from distance to no avail but the visitors had already done enough to ensure they can progress with just a point against Sturm next time out.
