"Our manager has been faced with some unexpected issues that could have very easily set the club back," Lerner told the club website.

"In watching him handle matters, along with our chief executive (Paul Faulkner), I've seen total loyalty and commitment to Aston Villa."

Villa announced on Tuesday that assistant manager Ian Culverhouse and head of football operations Gary Karsa had been suspended "pending an internal investigation", without providing further details.

Former players Gordon Cowans and Shay Given have been temporarily promoted to assist Lambert, and Lerner said that he had full faith in their abilities.

"Gordon, a Villa man through and through, has repeatedly stepped up to support the club regardless of the ask. Shay, too, has been unhesitating in answering the manager's call," he added.

"I couldn't ask for more from people who are up for this challenge and the very real obstacles we have to overcome, as is everyone at the club."

British media reports suggest that both Culverhouse and Karsa were suspended over a disciplinary matter.

Villa are currently in 14th place in the Premier League table, four points above the relegation places with five games to play.
