When Lambert took over in 2012 he trusted youth and signed the likes of Joe Bennett, Ashley Westwood, Jordan Bowery, Matthew Lowton and Christian Benteke, who were all under 24.
Brett Holman, Karim El Ahmadi, and Ron Vlaar were also brought in, but it was the likes of Barry Bannan, Fabian Delph, Ciaran Clark, Lowton, Westwood, Benteke and Nathan Baker who were trusted more often than not.
Benteke aside, Villa largely struggled in Lambert's first season, and but they eventually finished 15th, just five points above Wigan Athletic who were relegated.
However there was a feeling around the club the young squad would be all the better for the testing circumstances of the previous campaign, but the Villans were once again embroiled in a scrap for survival for much of last term also.
Leandro Bacuna, Antonio Luna, Ryan Bertrand, who arrived on loan in January, were all brought into the side last term, but Lambert's men were again forced to battle for most of the season as they finished 15th again, three points less than the previous campaign's 41 haul.
Randy Lerner's decision to sell the club has affected Lambert's transfer budget for the worse, and the Scot has the unenviable task of trying to improve his squad on a shoestring.
However are the deals for Joe Cole and Philippe Senderos an admission that his trust in youth is now on the wane?
Senderos and Cole at 29 and 32 respectively are hardly over the hill, but there is a feeling that both players are perhaps past their best, and the theory is particularly prevalent for the former West Ham United man.
Cole's career has been on the wane since he left Chelsea in 2010. He was sent off on his Liverpool debut and he never recovered.
A loan spell at Lille failed to reignite the career of the gifted Cole, and he was eventually moved on at a heft cost for the Reds in January 2013, despite signing on a free transfer.
Senderos was part of the Fulham side that were relegated and the Cottagers opted not to offer the Swiss centre-back a new deal, as they prepare for life in the Championship.
So as both vastly experienced Premier League players settle into life with the Villans, their arrival could perhaps be seen as a change in strategy for Lambert.
