Martin O'Neill 'confident' Roy Keane will benefit from his dual role

My view is if it doesn't impinge on the job here with Ireland, then in actual fact it will end up being good for him.I know that if we couldn't have made it work, he wouldn't have taken the job in the first place.If his commitments to us - both on the commercial side and certainly from my viewpoint in terms of the time working with players - is not impinged at all, then I'm happy for it to go ahead, genuinely happy.Villa have agreed to give him all that time with us and therefore I don't really have a problem with it.
