Villa went back to a 4-3-3 formation for Saturday's goalless draw at Hull City, having switched to a 3-5-2 shape for the victory over Manchester City a week earlier.
While he has favoured a four-man defence since late last season, Lambert is happy to have other options for certain situations.
And the Villa manager is delighted that he has versatile players and a strong enough squad to be able to be flexible with his system.
"The beauty of it is they can adapt," Lambert said in the Birmingham Mail.
"The lads know it (3-5-2). They played it last year, so they know how to do it. The good thing is we can change to different ways of playing.
"They can adapt to whatever we ask them to do. It all depends on who we're playing against and what players are fit, but we try to get a team to win.
"I played three at the back against Manchester City. Even though it was the first time this season, I thought they did exceptionally well."
