Bulut was a surprise scratch from the matchday squad just hours prior to last week's 1-1 draw against the Central Coast Mariners, with Brendon Santalab starting and Lachlan Scott given a spot on the bench.

Popovic revealed he wanted the mercurial striker to increase his effort in training to keep his position in the starting side.

Bulut has supposedly increased his training output but Popovic is yet to confirm whether he will give the forward another shot against the Glory.

"Kerem's been back training this week and he's training better than what he did last week, so that's a good improvement," Popovic said.

"We've still got two sessions to go, there's still a bit of work to do today and tomorrow to see who will travel."

Bruno Pinatares, another last-minute omission, has also been named in the squad though the Uruguayan midfielder has not played since being subbed off an hour into the Wanderers' round-one 4-0 Sydney derby thumping.

The Wanderers face a tough trip west in the knowledge individual errors have cost the seventh-placed team two wins and a spot in the top four.

Two weeks ago they settled for a 2-2 home draw with Newcastle after allowing a 2-0 lead to slip through their fingers, before last weekend committing the same crime to draw 1-1 with the Mariners.

"At the moment isolated mistakes are being punished," Popovic said.

"We have to make sure that if that happens again we've done well enough to still be able to win the game.

"Slowly but surely throughout the year, I'm sure you'll see less and less mistakes."
