Yeah, was at that memorable night at Ibrox!
Atmosphere definitely got to them that night and Parkhead will be the same tomorrow,Celtic rely on moving the ball quickly flooding players into midfield and penalty box, having a fast start and keeping the support up is crucial to their game plan, in European games if they get pressed and denied the space right from the start they start to unravel and the crowd get anxious.
Don't think they'll change that approach tomorrow as their support will be desperate for them to get off to a flier,Rodgers arrogance in that he thought they could go toe to toe and gung-ho with Dortmund on their own patch backfired spectacularly, so he might decide to be more cautious tomorrow(but I doubt it)
If Leipzig have learned how to deal with the atmosphere and don't allow them to get off to a flying start I'd expect them to win 2 or 3 - 1... or more preferably! Best of luck!!
