Joe Hart faces a nervous wait over his place in the Manchester City side after manager Manuel Pellegrini confirmed he has yet to decide who to pick at the weekend.
Hart has been under fire in recent weeks after some high-profile blunders and his deputy Costel Pantilimon was on Capital One Cup duty in Wednesday night's extra-time victory over Newcastle.
While it would be wrong to read too much into the Romanian's presence in the 2-0 win at St James' Park - he regularly features in the cup sides while Hart is rested - it was an impressive display.
Pantilimon denied Shola Ameobi in the first half and produced the standout save of the match when preventing Papiss Cisse from converting a one-on-one in the first period of added time.
It was enough to give the debate over Hart further legs ahead of Saturday's Barclays Premier League match against Norwich, though Pellegrini would only say that he had yet to make a decision on the subject.
"(Pantilimon) is a very good goalkeeper and he normally plays in the Capital One Cup and the FA Cup," said Pellegrini.
"This was a very important match for him. But I will start to think about the game against Norwich on Thursday. Today I was just thinking about winning this match.
"I think that we will talk tomorrow (about the team selection). One goalkeeper can play but the other will have our full support. We will think about it.
"(Pantiilimon) is a good player and is not playing too much because Joe Hart played this year and last year, but I trust him and for him and for the whole team to keep a clean sheet after six games is very important."
Pressed for further details about Hart's standing, Pellegrini responded curtly: "I have just told you I will think about that tomorrow."
Newcastle's downfall was a lack of precision in front of goal, with the Magpies enjoying the better of the play in normal time but failing to get on the scoresheet.
Both Ameobi and Cisse did put the ball in the City net, but each were judged offside when doing so.
By contrast, City strikers Edin Dzeko and Alvaro Negredo each converted in the first period of extra-time to secure a place in the last eight of the competition.
Home boss Alan Pardew was left frustrated at not being able to deliver the St James' Park faithful a morale boost after the Tyne-Wear derby defeat last weekend.
"I just feel for the fans really," he said.
"They were terrific. They didn't give us a hard time about Sunderland, they came to support the team and we responded to that.
"if you looked at us out there I don't think you'd say we were in bad form.
"We played well enough to warrant a goal and I couldn't ask more from the players.
"The performance level was really high but it was a hard match so it's a shame we didn't get our noses in front."
