“We need to have a good game and be concentrated for 90 minutes, stay focused and hopefully get something from the game.

“Bayer Leverkusen showed us in the last match that they can hurt us if we make mistakes. They’re a top team and we need to prepare for a massive and difficult game.

“But these are the nights and games you want to play and take part in and we just need to show it tomorrow.

“We have confidence in ourselves all the time, even after the game we lost 4-0, we didn’t lose our focus or concentration.

'We’ve had some good results since that match and we want to continue in this form.'

Now in his ninth season with the club, Bitton has become Mr. Versatile in his long career in the green and white Hoops.

Whether it’s in the heart of the defence, or in the engine room of the midfield, Bitton has shown his worth in a number of positions since signing in 2013.

This season, he has performed recently at the base of Ange Postecoglou’s three-man midfield. It’s a return to the position where the 30-year-old made his name and he hopes the shift further forward will see him add to his list of long-range goals in the Celtic shirt.

“I feel like I’m back in the 2015/16 season,” he said. “I feel good, but I’ve said before, whenever I get the opportunity to play I will do my best for the team to justify the faith the manager has given me.

“It’s not about myself, it’s all about the team and if we play well that’s more important.

“Hopefully I can hit one (long-range goal) tomorrow! If not, then the fans need to be careful because usually, it’s going row Z! But if one of them hits the target then it’s going to be dangerous.”
