Garde has failed to win any of his first three matches since taking charge at Villa Park, but he has still made a good impression, according to Guzan.
The American stopper says that he has been eager to guage his teammates’ opinions of the new boss, but everyone has only had positive words to say about him.
"You can see from his demeanour on the side of the pitch and from the way he carries himself in training, he has been very good," said Guzan.
"From speaking with the boys they have been really impressed in terms of the workrate and what he's putting into training. You want that leadership and guidance from the manager, especially the way things have been going for us.”
Garde has taken over Tim Sherwood, and his task of keeping Villa in the Premier League appears a hugely demanding one.
The Claret and Blues are winless in 13 matches, and they are already seven points away from safety – after a disastrous start.
Garde’s first three fixtures have largely been disappointing, with the side showing little signs of improvements.
The French boss kicked his reign off by helping his side claim a credible point against Manchester City, but since then results have taken a turn for the worse again.
Villa lost 4-0 to Everton, before being beaten 3-2 by Watford in their latest outing – and only a serious up-turn in their form will see them move away from danger.
