Martin O'Neill has admitted Celtic will need to have a "rethink" after a third loss in a week.
The Parkhead side lost 1-0 to Rangers, in a second defeat to their Glasgow rivals in just seven days, either side of a loss in the Europa League to Ferencvaros.
O'Neill admitted it had been a difficult week for Celtic as he reflected on the loss.

"Of course [it has been a bruising week]," he said on Sky Sports. "I don't think there is anybody pretty pleased with what has happened. It has been a pretty tough week for the football club.
"As history proves, it fights back from these things. It has been a tough old week for us to lose three games, but we are still two points in front.
"When the players come back from international duty, we will have a rethink."
