Two goals in 90 seconds from Gernot Trauner and Igor Paixao gave the Eredivisie side a dream start, with Anis Hadj Moussa and Santiago Gimenez adding the goals that keep it on course for a spot in the knockout stages.

The Dutch host needed only eight minutes to get on the scoresheet from a corner with Trauner's downward header wrong-footing Sparta goalkeeper Peter Vindahl.

The second came when Feyenoord's pressing stripped Kaan Kairinen of possession, and Paixao ran from the halfway line before bending the ball wide of the goalkeeper.

Hadj Moussa scored a stunner 30 minutes in, cutting inside from the right to fire a left-footed shot into the top corner. Feyenoord then failed to clear a long throw that was flicked onto Albion Rrahmani at the back post to make it 3-1 in the 43rd minute.

Gimenez restored the comfortable margin when he took advantage of a defensive slip to bundle the ball over the line from close range just after the hour mark.

Meanwhile, Sparta's second goal came from a cross in the 79th minute, which was steered into his own net by a sliding Thomas Beelen.

Feyenoord moved on to 10 points, while Slavia suffered a fourth defeat in six group games and has a tough task to avoid elimination.
