ROY Keane has left his role as Aston Villa’s assistant manager, the club has confirmed.
Paul Lambert’s former number two also holds the same position for the Ireland team, but has decided that combining both roles and making the necessary time for his family is impossible.
"Ultimately, my roles with Villa and Ireland and combining my commitment to these have become too much," Roy explained.
"It isn't fair to either Villa or Ireland, so I've made this decision.
"I'd like to thank Paul for giving me a great opportunity to come to a brilliant football club, I've really enjoyed my experiences at Villa and I wish the management team, the players, the supporters and the club nothing but the best going forward."
Keane leaves the club after less than five months in the role.
The Aston Villa boss will aim to secure a replacement as soon as possible, and the club will back his efforts to find a long-term replacement.
Manager Paul Lambert added: "Roy came to me this morning and he informed me that, ultimately, the difficulty of combining both roles has prompted his decision, which I respect totally.
"In the brief period we have worked together he has been great in the role and I understand his reasons for leaving."
CEO Tom Fox said: "We thank Roy for his time at the Club and we wish him the best with Ireland.
"Our focus now will be on working with Paul to identify the right person to work alongside him and to help us continue on our journey to return the Club to its rightful place in the Premier League."
