Holman was a regular starter for Villa in the first half of the season but the midfielder has made just three substitute appearances since the middle of January.
And, when he was away on international duty with Australia last month, the 29-year-old said he was finding the lack of action frustrating.
But Lambert is not angry with Holman and told the Birmingham Mail: "I've had a good chat with him.
"He is an experienced player and has done really fine since he's been here.
"You don't want people to sit and be happy when they are not in the side, you want them to be unhappy.
"He couldn't get in because Charles (N'Zogbia) was playing extremely well. I've got to pick a team that can win a game."
Lambert also took the opportunity to praise young midfielder Ashley Westwood, who signed from Crewe last summer and has enjoyed a successful first campaign at Villa Park.
"Coming from where he was and to do what he has done here is absolutely phenomenal," said Lambert.
"Players like Christian Benteke get all the headlines and I suppose a lot of the work Ashley does goes unnoticed by some, but not by me.
"The team functions when he's getting the ball and giving it.
"I think that maybe now, with the way he's playing, he's finally starting to get the recognition he deserves."
