Republic of Ireland manager Martin O'Neill has revealed that he has not read his assistant boss Roy Keane's new autobiography, but expects "furore" over his musings.

The former Manchester United captain's book titled The Second Half, which contains criticism of his former manager Sir Alex Ferguson, will be released tomorrow.

The 43-year-old, who works as assistant boss at Aston Villa, has rejoined the Ireland setup for this week's Euro 2016 qualifiers against Gibraltar and Germany.

"It obviously was going to cause some sort of furore at some stage or another, the very fact he put his name to this book would suggest that it's exactly what would happen," the Daily Mail quotes O'Neill as saying. "It's there and it doesn't matter."

Ireland will take on Gibraltar on Saturday.
