Guzan, 31, struggled for form over the first half of the season before losing his place to summer signing Mark Bunn last month after committing a string of goal-costing errors.
Bunn proceeded to record three clean sheets in his first five Premier League starts for the club – one more than his American counterpart managed in the previous 20 matches, while conceding just three goals in the process to help Garde’s men pick up seven points.
However, the former Norwich stopper had a game to forget in the recent clash with Liverpool when he saw the visitors put six goals past him to condemn Villa to their heaviest home defeat since 1935.
He was certainly let down by his defence on the day, but a fundamentally poor mistake to let James Milner score direct from a free-kick in the first half still promoted questions about whether the Camden-born keeper is cut out to be a starter at the top-flight level.
Garde admitted last week that Guzan could return to the line-up at some stage this season after stressing that the US international still has a future with the club, but his latest comments ahead of Saturday’s trip to Stoke City suggest that a change will not be happening any time soon.
Asked at his pre-match press conference whether he could go back to Guzan after the Liverpool mauling, the Villa boss told reporters: “It’s not all about the goalkeeper. I’m not sure that Mark was at fault for many of the goals we conceded.
“He was for some but not all of the goals, of course. A football team is also about stability. With his position and the centre-backs it’s all about stability, so there you’ve got your answer.”
Meanwhile, Garde openly admitted that he thought some of his players were not showing enough commitment amid the club’s battle to avoid the drop and acknowledged that certain unnamed individuals would be out of the first-team picture if he was not so short of options.
"We don't have room for manoeuvre with so few players," he said at his press conference. "Sometimes it's about fighting and commitment. It's the first thing professional players should have on the pitch, how can you be confident if you are not fighting?
"I don't see the commitment from all the players every day in training sessions. If I had the choice of other players I would like to select, I would like to – but I don't have the possibility.
"I have to find the right training session and words to make them committed every day."
Villa currently sit eight points from safety at the foot of the Premier League with only 12 fixtures left, having recorded just three wins and scored a division-low 20 goals in their 26 games.
