The 42-year-old will continue to work as the Republic of Ireland No2 under Martin O’Neill as the former Manchester United captain looks to balance the two roles.
I’m really looking forward to working with him and I’m delighted that he’s here
“I am delighted to be joining Aston Villa and I look forward to what promises to be an exciting challenge,” said Keane, who has previously managed Ipswich Town and Sunderland.
“I am grateful to both Villa and the Football Association of Ireland for making this happen and I would like also to thank Martin O’Neill.
“I am relishing the prospect of linking up with Paul Lambert and combining both roles to the full advantage of both Villa and Ireland.”
44-year-old Lambert, whose Villa side finished in 15th place last season, expressed his delight to add Keane to his coaching staff.
“Roy has a great knowledge of football, on the coaching side as well, and he’ll be a great asset and a big help to everybody here at Aston Villa,” Lambert said.
“I’m really looking forward to working with him and I’m delighted that he’s here.
“As a player, he was one of the most accomplished in the history of the Premier League and he’s brought that experience gained over many years into his career in coaching and management. The players will love working with him.”
