Belgian side Genk beat Sassuolo 2-0 on Friday to leapfrog Athletic Bilbao and claim top spot in Group F of the Europa League.

The match was postponed from Thursday because of thick fog.

Brian Heynan put Genk ahead near the hour mark and Leandro Trossard doubled the visitors' lead 10 minutes from time, shortly after Sassuolo's Luca Mazzitelli blasted a long shot off the crossbar.

Genk finished the group stage with 12 points, two more than Athletic, who also advanced to the round of 32.

Rapid Vienna finished third with six points and Sassuolo, who had already been eliminated, came last with five.
