Republic of Ireland manager Martin O'Neill has revealed in today's press conference that Roy Keane has had 'an informal chat' with Celtic's majority shareholder Dermot Desmond about the former Manchester United captain becoming the Glasgow giants new manager.

Dermot Desmond, who was influential in getting O'Neill and Keane to manage Ireland, has had discussions with Roy Keane about becoming Neil Lennon's successor at Parkhead. However, it is understood that Celtic have yet to offer Keane the post and are still said to be considering other candidates. 

The former Sunderland and Ipswich Town boss had been out of management until agreeing to become Martin O'Neill's assistant manager in November. He led Sunderland out of the Championship in his first season as manager, before struggling, first with Sunderland and then with Ipswich, with players at both clubs allegedly unhappy with the fiery Irishman's treatment of his players.

Celtic defender Charlie Mulgrew was quoted today as saying: "I'm sure he'd be a good man for the job. As a player, I think the club needs a big character and he definitely fits the bill."

Keane spent 12 highly successful years at Manchester United where he was widely regarded as one of the finest midfielders in Europe. He finished his career at his boyhood club Celtic before moving into management. It remains to be seen whether he would like to manage his heroes.
