Looking at these fixtures, it looks mouthwatering especially the games against Chelsea and the game against Bayern Munich, these two games is their most difficult fixture if you ask me which of the games they are going to be tested the more.
Don't forget about PSG, last season's UCL winners, who could also provide a nice surprise. Indeed, they share a fixture with Bayern Munich and several other top clubs. But for now, Bayern Munich, PSG, and Chelsea pose challenges that will be troublesome for Barcelona, and vice versa for those clubs.
