The Clarets host Oxford United tonight looking to get back to winning ways after playing out back-to-back 0-0 draws.
It leaves Parker’s side third in the Championship table, three points adrift of Sheffield United in second.
As for the U’s, they extended their unbeaten run to nine games under new boss Gary Rowett following a 1-1 draw against Bristol City, who ended the match with nine men.
Burnley continue to sweat over the fitness of Josh Brownhill and Luca Koleosho after the duo missed the Pompey game with knocks. Elsewhere, they remain without a number of injured players.
With that in mind, here’s how we think the Clarets will line up:
5. LB - Bashir Humphreys
Lucas Pires struggled a bit at Fratton Park, especially defensively, so Humphreys is likely to return at full-back. Photo: Ryan Pierse
6. CM - Josh Cullen

7. CM - Josh Laurent
The midfielder had a bit of an off day against Pompey, but with Josh Brownfill a fitness doubt he's likely to get the nod again. Photo: Matt McNulty
8. CAM - Hannibal
Jeremy Sarmiento missed his chance in the number 10 role on Saturday and, with Josh Brownfill a doubt, Hannibal could feature a little further forward. Photo: Ryan Pierse
