This will be a challenging week for Celtic and it will be interesting to see how the Hoops perform v a testy German team that will definitely "give them a game", much like RB Salzburg did in Austria. The Hoops have a League Cup semi-final at the end of the week but I think this game, at a higher level of footie, is far more important to Rodgers although he'll be looking to win both matches anyway. Celtic are suddenly "on a roll" and I'd say confidence will be reasonably high. However, top priority - don't lose the match and keep up the positive momentum.
