After a disappointing campaign last time out Alex McLeish was axed and the Villans moved to bring in the promising Scottish manager, who had excelled with Norwich City.
And Guzan, who has been drafted in to the team by Lambert, believes the future is bright for Aston Villa.
He told the club’s website: “I was excited about the changes at the club and what was going to happen with the players and where the manager wanted to take the club and the direction he wanted to take it.
"It's been good so far. We are definitely a club that have no longer just got an aim for the short-term, but also the long-term as well. That's a good sign for everyone.
"There's a changing of the guard, if you will - in terms of bringing in younger players. We want to win games and move our way up the table and have a good year this year obviously.
"Ultimately it's going to pay off in a few years down the road. It's not a one-year plan and let's go off, we want to build something special.”
While midfielder Marc Albrighton added that the players are learning from the former Celtic and Borussia Dortmund midfielder, who won the Champions League in 1996 with the latter.
He said: "The gaffer has come in and put a stamp on the club in terms of what he wants and what he expects. He's done that straight away which I think is perfect.
"As a manager he has set his standards and it's up to us as players to live up to them.
"With the squad we have and the set of lads we have, we will be doing everything we can to ensure that.
"He has had a brilliant career and it excites all of us, not just the young, but the older players also, to be working with him.
"It is fantastic, an honour, to say our manager and reserve team manager have won the European Cup. We're bound to learn from these guys!
"It passes on a good vibe, too. He's not bought his medal in yet, though!
The winger also revealed his manager is still looking the part when he joins in on the training pitch.
Albrighton added. "The gaffer joins in a few sessions and you can see the touch is still there. It's only his pace that's not there. He reckons he had me in his pocket the other day. That was good fun."
