Martin O’Neill is set to announce he is leaving as Celtic manager, according to reports.

Gordon Strachan, the former Coventry and Southampton manager, is being tipped to take over at Parkhead.

“My information is that Martin will certainly quit after next weekend’s Tennents Scottish Cup final,” said BBC Scotland’s Chick Young.

“He will be succeeded by Gordon Strachan.

“But the Stock Exchange will have to be informed first of all – that is why there has been no official reaction from Celtic.”

Northern Irishman O’Neill has been in charge at Celtic since June 2000, but his wife Geraldine is ill and it is expected that he will stand down in order to look after her.

O’Neill’s side relinquished their hold on the SPL title in dramatic circumstances on Sunday. Requiring a win in the final match of the season to retain the title, Celtic surrendered a one goal lead with two minutes remaining, eventually going down 2-1, to hand the title to arch-rivals Rangers.

On Saturday they play Dundee United in the Scottish Cup final – in what may be O’Neill’s final game.

O’Neill said after Sunday’s defeat to Motherwell: “I have no comment to make on my future. This outcome does not come into my thoughts on my future.”
