Celtic's fit-again midfielder Niall McGinn has piled praise on keeper Fraser Foster for preserving their Co-operative Insurance Cup status.
The Bhoys were given a cup fright by St Johnstone on Wednesday before eventually running out 3-2 winners at McDiarmid Park.
Forster came under fire for his poor clearance that led to Kenny Miller's first goal on Sunday, although he was back to his best against the Saints.
The on-loan Newcastle United keeper pulled off a string of saves to ensure Neil Lennon's side booked their place in the semi-finals of the competition.
"Big Fraser Forster pulled us out of some sticky spots against St Johnstone," McGinn told the Evening Times.
"He came in for some flak after Sunday's game, but he has been a player at Newcastle United and other big clubs in England. He has been about.
"When called upon, he can pull us out of holes. He showed against St Johnstone what he is capable of. We are all happy to have him in goal.
"Our major issue after Sunday's result was just to bounce back with a win and we managed to do that."
Although Celtic conceded twice against St Johnstone, McGinn was pleased with the team's defensive efforts on the night.
However, he knows they need to tighten up in the long run and that cutting out mistakes at the back will benefit them.
"I thought we defended well at times, but we made a few sloppy errors at the back which allowed them to get back into the game," he continued.
"Our defence has been brilliant so far this season so the last couple of games have been disappointing. We definitely need to work on that area.
"Up top and in midfield we are doing pretty well at the moment, but we have been leaking stupid goals in defence in the last couple of games and it has been costing us dear.
"We have to keep pushing ourselves hard in training and try to improve as much as we possibly can. We will need to perform better if we hope to get three points against St Johnstone on Saturday."
