It's in the Daily Mail and we've also had a few emails in. We know for sure that O'Neill was approached this week and everything is now pointing to a positive outcome.

Martin O'Neill is a very good manager and will get the best out of the players he has. He has proven during his managerial career that he knows what he is doing.

After his playing career O'Neill began a career in football management, initially at Grantham Town F.C. in 1987. After a brief spell at the helm of Shepshed Charterhouse, he managed non-league Wycombe Wanderers F.C., whom he took into the League in 1993 following a bad-tempered and hard-fought campaign in 1992 alongside Roy McDonough's Colchester United[1]. He later managed Norwich City but resigned on a matter of principle before he'd had a chance to make an impact.

He joined Leicester City F.C. in the second half of the 1995/96 season. He achieved great success at the club, gaining promotion via the play-offs to the Premiership in the same season as joining the club. Leicester finished in the top half of the Premiership in every season O'Neill was manager. They also won the League Cup under O'Neill in 1997 and 2000.

During his time at Leicester, O'Neill held talks to become manager of Leeds United F.C. but declined the job after thousands of supporters held up placards saying "Don't go Martin!" in an effort to make him stay.

O'Neill did eventually leave Leicester in 2000, taking over from the team of John Barnes and Kenny Dalglish to become manager of Celtic F.C. In his first season they won the treble and more recently he guided them to the final of the 2003 UEFA Cup. In his five seasons there, he won three League titles, three Scottish Cups, and a League Cup. Leicester have twice been relegated from the Premier League since his departure.
