Vincent Kompany’s men performed well in the first-half and were unfortunate to find themselves a goal behind at the interval.
However, they struggled a little during the second period and Genk made them pay with a second late on.
Despite that, it was a good workout for the Clarets against tough opposition, with their Belgian opponents in Champions League qualifying action on Tuesday.
Here we take a look at how Burnley’s players performed during last night’s encounter...

10. Vitinho - 6/10
Did okay in a more advanced position than he’s accustomed to on the right wing before being replaced by trialist Andros Townsend. Photo: Nathan Stirk
11. MAN OF THE MATCH: Anass Zaroury - 8/10
Burnley’s standout performer. A bag of tricks and beat his man regularly during the first-half. Not quite as impactful in the second. Photo: Matt McNulty
12. Lyle Foster - 7/10
Looked lively at times, especially during the first-half. Worked especially hard to win the ball back on numerous occasions. Photo: Matt McNulty
