Tuesday's 2-2 draw at Swansea left Lambert with his head in his hands after Danny Graham struck a late leveller for Swansea, but the Scot could at least take some comfort that the Villans had not suffered a fourth-straight heavy defeat.
Prior to their Liberty Stadium visit, Villa had shipped 15 goals and scored none in their previous games and, truth be told, they should have conceded a handful more during an opening half-hour where Swansea threatened to run amok. However, Lambert said: "We have been better than we have shown in the last three weeks."
Villa, fielding their youngest side in a Premier League game with an average age of 23 years and 119 days, showed grit to steady the ship and should have hung on to claim a valuable win after Andreas Weimann and Christian Benteke's penalty put them ahead.
Lambert, without the likes of Darren Bent, Gabriel Agbonlahor, Nathan Baker, Richard Dunne and Ron Vlaar through injury, will look to strengthen his squad in January, but feels he has a group of young players who will serve the club well in the long term.
Lambert added: "A result like this will always be a building block, it's a long-term job I have here. It's a massive job and the football club will be better in the future.
"We do have experience in the squad but some lads are injured at the minute, the club has been in this position before so it is not new to them.
"We know you have to earn the right to go up the league table but the future of the club will be really good.
"I have a great belief in what is happening here."
