Thousands of Celtic fans have already descended on Germany, and with kick-off fast approaching at 8pm, the excitement is palpable. The atmosphere inside Signal Iduna Park is expected to be electric, and the Green Brigade’s display is sure to add to the spectacle.This latest move by the ultras group is another example of Celtic’s unmatched support, both at home and away. The Hoops faithful are well-known for their vocal and visual backing, and tonight’s game will be no exception as the Green Brigade urges supporters to take part in their choreographed show of strength.
