Villa crashed to a second successive heavy Premier League defeat on Boxing Day, being thrashed 4-0 at home by Spurs three days after suffering a humiliating 8-0 hammering at Chelsea, and are now only three points above the drop zone.
And as far as Villas-Boas is concerned, Villa must stick with the Scot as manager.
"They were a different team at the beginning," said Villas-Boas - who, like Lambert, was appointed to his present post over the summer.
"When Paul changed the structure to five at the back the results improved for them and they managed to get some important ones.
"I think for them now it is important to find stability defensively, looking at what is happening.
"I think Paul is the right person. He is developing a very young team, and it has nothing to do with teams of the past.
"So hopefully, by him being given time to do that, Villa can achieve the results they want."
