Celtic face Barcelona at Parkhead in the Champions League on Wednesday night, live on BT Sport with a 7.45pm kick-off.
The Ladbrokes Premiership leaders, who play Aberdeen in the Betfred Cup final on Sunday, were heavily beaten in the Nou Camp on matchday one but have since drawn with both Manchester City and Borussia Monchengladbach.
Boss Brendan Rodgers told the Celtic View: "Make no mistake about it, we are playing against one of the best teams to have ever played the game and a front three that is as good as there has ever been.
“That’s the size of the task we have but we always go into every game with a quiet confidence that we can do well and we showed in the Man City game that if we can reach that level of performance and get a bit of good fortune then you never know what can happen.”
