11月3日，24直播网报道，据巴塞罗那队跟队记者胡安·何塞透露，在当前球队所面临的挑战中，弗里克最为关切的是他们在欧洲冠军联赛中未能实现一场零失球。
The player Juan Jesus revealed that the issue that is causing the most concern for coach Frick — a point he emphasized once again today — is the team's inability to secure a clean sheet in European competitions. The last time Barcelona managed to keep their goal unpenetrated in the Champions League was over a year ago.
弗里克着重指出，在球队无球状态下，每位球员都需保持极高的警觉性，并全身心投入到防守之中。对于今晚的赛事，这位德国教练强调球队必须保持极高的专注度，对任何纪律松懈的行为都绝不容忍。
