Celtic are back on the big Champions League stage and they arrive in Bergamo with a big point to prove to eyes across Europe.
Brendan Rodgers and his troops arrived in Dortmund on matchday two with their tails up after a flawless start domestically and a thumping opening day triumph over Slovan Bratislava under the lights at Parkhead.
