Zian Flemming struck twice off the bench during the extra 30 minutes as the Clarets took longer than expected to claim an otherwise deserved victory.
Scott Parker opted to make all 11 changes, but they were still a number of eye-catching displays.
Here’s how Burnley’s players rated:
9. Luca Koleosho - 7/10
End product wasn’t always quite there but he consistently looked like Burnley’s biggest threat. Came close with two or three good openings. Photo: Warren Little
10. Lyle Foster - 8/10
Deserved his goal, even though it took two attempts, following an impressive display out on the flank. Could left wing be an option going forward? Photo: Warren Little
11. Ashley Barnes - 6/10
Not involved a great deal on his second Burnley debut but missed a golden chance to win it in the final minute of normal time. Photo: Alex Livesey
12. SUB: Hjalmar Ekdal - 7/10
For Egan, 72 A welcome return from injury for the Swedish international, playing his first football of the season. Gave very little away. Photo: Stu Forster
