Graham: O'Neill convinced me about Sunderland move
The striker is waiting for his first start.
"He was a very big part in my reason for coming when I first spoke to him," he said. "The way he comes across, his man-management skills and his tactical knowledge of the game. He's managed at the top for a number of years. I'm pleased to be working with him now and hopefully getting to know him a bit better over the coming weeks."
