Villa have 10 points from their opening eight games but have already played five of the Premier League's 'big six' and enjoyed wins over Arsenal and Manchester City.
Everton are next up and Lambert is looking forward to testing his side against a team that they should be looking to match at the very least.
"The thing for us is that in our start to the season we've played five of the top six which is an incredible thing to come through," said Lambert.
"You need a bit of respite at certain times from that. You can't keep going like that.
"The only one we haven't played yet is Manchester United so when you look at it like that, our points tally is pretty decent.
"I know this will be a hard game as Everton have been going well. They have a different way of playing now. It'll be a hard game but we're at home.
"They've have got off to a great start but those players have been there for a long time under David (Moyes).
"They're ahead of us regarding the stability they've had for a number of years now. Look at their defence and it's been there for years, the goalkeeper has been there for years, all the lads have known the football club for that length of time.
"They're ahead of us on that side of it, the stability. They were there under David and he did great at Everton. It was probably a good club to go in at that time but Roberto has done well."
