With veteran keeper Adriano Basso also in his thoughts, boss Nigel Pearson admits the 21 year old is under pressure to hold on to his place.
"I suppose what the other night highlights is the pressure that goalkeepers are under," he said.
"If they make a mistake, you're more liable to cost your team a goal.
"I'll make the decision based on what I feel is the best side to start tomorrow."
Gulacsi was seen as the obvious choice to become City's regular number one after he arrived on a year-long loan deal from Anfield last month.
Pearson, though, made a point of defending Gulacsi role in the Leeds defeat.
"Every player, whether they're young or some of the older players, can dip in confidence," he added.
"It's always how you respond to criticism. It's not about what other people make of you, you've got to go out and perform.
"That goes for all the players. That's everyone.
"People make mistakes. Everyone makes a mistake.
"Unfortunately if it's a mistake that costs you dearly you're going to be under scrutiny. He'll have to recover from that, as every player does.
"We win as a team and we lose as a team. Yes it'll be highlighted because of the position he plays in but we weren't faultless apart from that."
