Paul Onuachu is now the undisputed top scorer in the Belgian league with 12 goals after he grabbed a brace in a 5-1 thrashing of Cercle Brugge, while his club KRC shot to top of the table.
Onuachu opened scoring after nine minutes and he got his brace just before the interval.
Last season, he scored nine goals in his debut campaign in Belgium.
He is widely tipped to be Goal King this term.
Tonight’s big win has pushed Genk to top of the standings provisionally with 28 points from 14 matches.
Genk have won their last six matches.
