The Villans' manager also eulogised over Matthew Lowton's "world class" strike after witnessing his side move out of the relegation zone with victory at the Brittania
Gabriel Agbonlahor gave the visitors the lead in the first half but the Potters looked set to steal a point late on when Michael Kightly drew Stoke level with just ten minutes remaining.
However, a stunning long-range strike from Matthew Lowton and a third from Christian Benteke sealed a 3-1 victory and Lambert believes his team are profiting from playing with confidence in front of goal.
"We’re playing well at the minute [and] there’s a lot of confidence about the team," Lambert told reporters. "The crowd today were outstanding again but I thought we were outstanding today."
"I think we play without a fear. We’ve got some terrific footballers at the club, really good, and a lot of them are still learning their trade and trying to get results.
"From my own team’s point of view we play the game the right way, and if you can play without fear and a freedom it’ll certainly help you."
Lowton scored his second goal for the club to give the visitors the lead with a strike that was reminiscent to his finish at home to Swansea earlier in the season; Lambert believes the strike will struggle to be beaten for quality this term.
He continued: "I don’t think you’ll see a better goal in Europe let alone Britain. The technique and the finish were world class.
"He’s not missed one minute for us this season since coming from Sheffield United. He’s still learning.
"He scored a similar goal against Swansea at the beginning of the season and I thought that one [today] was absolutely outstanding."
