Celtic showed they will be competitive in Champions League despite defeat to Feyenoord, insists Brendan Rodgers

Brendan Rodgers felt his Celtic team showed they can compete at Champions League level before inexperience played its part in their Group E opener against Feyenoord running away from them following two red cards inside five minutes.

Joe Hart saved a penalty in between the red cards before Feyenoord went on to win 2-0 in Rotterdam.
