Republic of Ireland coach Martin O'Neill says assistant manager Roy Keane has his full confidence.

Cardiff City midfielder Harry Arter is missing from this week's squad after a bust-up with Keane.

O'Neill said, "I have got total confidence in Roy.

"Roy Keane wants the best for the Republic of Ireland, as I do. We managed to get to the Euros and the World Cup play-offs and Roy has been a great part of that.

"I wasn't there during the discussion (row), but I've heard the sides of the story. Jon Walters is coming in. I think you have to consider that.

"I took Roy on because I wanted him to display the things that he has shown over the five years. I am not an apologist for him - he can speak for himself."
