The Clarets broke the deadlock late on through Josh Brownhill following this tight and edgy encounter at Turf Moor.
But, for the second week running, Muric cost his side with a real horror moment, allowing Sander Berge’s back pass to go under his boot and into the back of the net.
In being held to a 1-1 draw, Burnley remain six points adrift of safety with only five games remaining.

11. David Fofana - 5/10

12. SUB: Charlie Taylor - 6/10
