Aston Villa coach Roy Keane admits his job with the Republic of Ireland takes priority.
The former Sunderland and Ipswich boss insists he will put Ireland first if he feels he is unable to combine both roles.
"I feel that if I am taking my eye off the ball with Ireland, then I will leave Aston Villa," said Keane.
"There is no doubt about that. I have told Paul Lambert that, told Martin that and told the FAI that.
"But at the moment, it is OK. If we lose three or four on the spin (with Ireland), then I will leave Villa.
"But I'm still getting to games, I am on the training pitch at Villa, improving and am working with Irish lads like young Jack Grealish.
"The guilt would kill me if I thought 'I am on a cushy one here'. I couldn't work that way.
"I said before that you could do only one job, but I said that because I was only in the Ireland job a short period of time.
"I didn't just jump into it with Villa. I sat down with Paul Lambert, had a think, and sat down Martin and the FAI and thought, I can adapt to this.
"It felt like a full-time job, but, having been in the Ireland job a while, I felt I could manage to do both."
