The Scot has built one of the youngest squads in the Premier League since arriving at Villa Park from Norwich City last year, with an average age of around 23 years.
Lambert suggested that he is comfortable with the means given to him by chairman Randy Lerner, despite being somewhat restricted in the transfer market.
"Randy has been great and (chief executive) Paul Faulkner have been great but we won't be able to do what you would call a massive signing," Sky Sports News quotes the 44-year-old as saying.
"We have to look at the market, the young lads. We give them an opportunity and hopefully they take it."
