Celtic will “come together and support” manager Martin O’Neill after a “painful” week for the club, chief executive Michael Nicholson has said.

O’Neill had indicated that he would use the international break to consider his future following two defeats to Rangers, either side of a home loss to Ferencvaros in the Europa League.

In the wake of Sunday’s 1-0 derby defeat at Celtic Park, 74-year-old O’Neill had said “it might be time to wrap it up”.

However, Nicholson suggested the club will rally round the manager who has delivered nine trophies over two spells.

His remarks came with the latest financial figures revealing a drop of nearly £33m in revenue.

A loss of £4.8m is largely down to the failure to reach last year’s Champions League and Celtic have missed out again, squandering a 4-0 aggregate lead in their play-off with LASK last month.

“Having started well in the Premiership this season, we experienced disappointment in the Champions League play-off,” said Nicholson in a written statement accompanying the financial results.

“Reaching the league phase of the Champions League is an objective for us all, and we are sorry not to have achieved it.

“On top of that, the losses in the last week have been painful for us all. We will now come together and support Martin and the players, as we focus our efforts on achieving success domestically and in the Europa League.”
