Lerner splashed out almost £23million to help Lambert rebuild the squad during last summer, with the accent on bringing in up and coming young talent.
There had been encouraging signs up to a fortnight ago with Villa reaching the Capital One Cup semi-finals via a 4-1 success at Norwich and then winning 3-1 over Liverpool at Anfield. That victory was achieved with a side having an average age of less than 24 and was the youngest ever fielded in the Premier League.
But Villa's lack of experience, due in part to a lengthy and growing injury list, has been highlighted over the festive period with 15 goals conceded without reply in three games.
Lerner and Lambert held talks about the approach to be taken next month before and after Saturday's 3-0 home defeat by Wigan left Villa only a point above the Barclays Premier League bottom three.
Lambert also has the option of trying to offload some of the players who had only played a bit-part role even before becoming injured to bolster funds.
The likes of record signing Darren Bent, Charles N'Zogbia, Shay Given, and Stephen Ireland have made only a handful of starts this season. Villa have also missed the leadership qualities of skipper Stiliyan Petrov who continues to battle against acute leukaemia.
Lambert retains the backing of the Villa fans and the boos after the latest setback against the Latics were more in frustration at a poor performance rather than being aimed directly at the Scot.
There is also no suggestion his own position is under review with Lerner recognising the long-term nature of the rebuilding job needed at Villa.
