The Australian Player of the Year opened his Villa scoring account when he found the back of the net in the eighth minute of the Birmingham club's 1-1 draw with QPR at Loftus Road on Saturday and the showing was not lost on his boss.
"I thought it was a fabulous strike. He's only been here a short time," said Lambert.
"It's a different environment for him and he's still adapting. His energy levels are extremely high. He's been excellent so far."
Holman joined Villa from Dutch club AZ Alkmaar on a free transfer in the summer and has since made 15 Premier League appearances - 10 of which have been starts - and one substitute appearance in the Capital One Cup.
