Former Sunderland manager Roy Keane is keen to get back into the coaching game.

Recently, the Irishman has been studying various techniques of some of the best sporting clubs around including the New Zealand rugby union side and Portuguese football club Benfica in a bid to learn more about the caper.

"I wanted to know the methods of Benfica's work from the juniors to the first team. Benfica have some of the best faculties on the continent," said Keane.

"My future? I'm hopeful because I want to get back into management in the summer.

"I don't know where that will be, but I'm keeping all my options open and wouldn't dismiss the possibility of working abroad."
