However, the former Dundee man still looked nervy following his harrowing experience at the hands of Holland in Amsterdam last week, when he and his Scotland team-mates were hammered 6-0 and O’Neill is confident that the former Coventry stopper will be fit.

“He didn’t do any training this morning because we kept him out as a precaution. He’s improving and we’ll see how he is tomorrow morning but he is pretty hopeful,” said O’Neill.

The Hoops boss must also decide whether to recall Scotland’s other Dutch starter, Jackie McNamara, or stick with Johan Mjallby after recently recovering from injury.

The Swedish defender got a full game at Tannadice and the Celtic boss is confident that he would not let him down against Bayern.

“I am pleased that he did play the game,” explained O’Neill.

“If it’s necessary for him to play, at least he has the psychological boost of 90 minutes beforehand which was one of the pleasing aspects of Saturday.”

Celtic can send the 2001 European champions crashing out at the group stages for the second-consecutive year if they win at Parkhead and Lyon beat Anderlecht in Brussels.

But despite a far-from-convincing win over city rivals 1860 Munich at the weekend, O’Neill warns that Ottmar Hitzfeld’s team will be even more of a threat after their home defeat at the hands of Lyon on November 5.

“Bayern Munich are a top-quality side and probably think that they might have had more points in the group,” O’Neill added.

“So it is balanced at this minute and everybody’s going to try and win the game and we will be positive and go for everything.

“Hopefully if we get a bit of luck on the evening it will go our way, but it’s going to be hard.

“They will be more dangerous and they will always have a feeling that they can fall back on their last game [against Anderlecht].”

Celtic’s fans will expect their team to kill off Bayern given the Hoops’ incredible unbeaten home record at Parkhead stretching back to a defeat to Ajax in August 2001.

The Bundesliga outfit have failed to live up to their own high standards but O’Neill admits his side will have to be at their best to beat them and cannot depend on the famous Parkhead atmosphere to scare the superstars of Munich.

“The expectations here are such that if we win a game of football people feel we have won the World Cup and if we lose then it’s like we will never win again,” he said.

“But the players will cope the best we can and the players know they have to be absolutely at their best to win the game tomorrow night.

“The atmosphere on European evenings are definitely special but we are not the only team in the world that has 60,000 people shouting for them.

“The atmosphere is absolutely electric and seems to get better but these Bayern Munich players have played in massive games before.

“They have played in World Cup finals and European Cup finals so I wouldn’t be sure that other players have a fear factor coming here.

“These records can all change at any given moment and records are there to be broken. We have no divine right to win this game and the players know that.”
