The Aston Villa manager was encouraged by the impact of Brett Holman, Matthew Lowton and Karim El Ahmadi and also took time to praise the club's supporters against Burton Albion
Lambert singled out the displays of Karim El Ahmadi, Brett Holman and Matthew Lowton for praise and thanked the fans for the vociferous support the team received at the Pirelli Stadium.
Villa had to come from behind to beat the home team, with Holman bagging the winner after Marcus Holness had cancelled out Robbie Weir's opener with an own goal.
"It was a great goal from Brett, it really was," Lambert told Villa's official website.
"I thought Matty never broke sweat. He was excellent. You wouldn't think he's just come out of League One. His performance was really pleasing. He will do great for us.
"And I thought Karim, everyone can see he's got quality in the middle of the park."
The 43-year-old appreciated the enthusiastic support the team received and emphasised the importance of the fans in ensuring a strong season at Villa Park after a disappointing 2011-12 campaign.
"The fans were brilliant," Lambert enthused. "I could see that, I could sense the passion they've got.
"Hopefully we can give them something back. We will certainly need them. Today they were excellent. The following today was great.
"It is a huge football club. I am under no illusions how big a job it is. With what's happened over the last few years we'll try to pick it up and the crowd will certainly get behind the team."
Lambert also took the opportunity to clear up some injury worries for Villa after Stephen Ireland, Fabian Delph and Marc Albrighton were all forced to miss the friendly.
Lambert suggested there would be quick returns for Ireland and Delph, but admitted that Albrighton's situation was more complicated.
"Stevie got a really bruised big toe on Thursday," Lambert explained. "That's why he missed that. Fabian felt his knee a little bit. I don't think it's too much.
"Marc is a little bit more difficult at the minute. He could be a little while which is a bit of a blow for us but we will have to wait and see."
