Chief executive Michael Nicholson has stated the Celtic board will continue to back Martin O'Neill.
The Parkhead side have had a painful week after losing back-to-back games against Rangers in the Premier Sports Cup and the league, losing their momentum from a previously unbeaten start domestically. There was a Europa League defeat to Ferencvaros in between.
It comes weeks after crashing out of the Champions League at the play-off stage, throwing away a 3-0 first leg lead on LASK.
Recent results have raised questions over the future of O'Neil, who agreed to carry on after stabilising the club last season.
But the club look set to get behind the 74-year-old.

After Celtic's accounts were published, Nicholson said in a statement: “The final weeks of the Premiership season; the final match at Celtic Park; the Scottish Cup final; these will live long in the memory for Celtic fans, whose support was a decisive factor.
“I thank Callum McGregor and all of the players and staff for their hard work and determination throughout the season that made the success possible.
“As the Chairman has noted, the environment was unstable, following Brendan Rodgers’ resignation and our decision to move on from Wilfried Nancy.
“We owe a debt of gratitude to Martin O’Neill and his management team, who stepped up for Celtic, twice, and who guided the team to success.
“We were therefore delighted that Martin agreed to lead the Club again this season and we have worked with Martin and his team over the summer transfer window to invest in the squad.
“Having started well in the Premiership this season, we experienced disappointment in the UEFA Champions League play-off.
“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.”
