#1 FC Barcelona
If we decide to rate the most impressive clubs in the UEFA Champions League so far this season, not many teams will find themselves in the same category as Catalan giants, FC Barcelona.
The Blaugrana have been at an amazing level since the tournament kicked off this term, opening their campaign in style with a fantastic 4-0 victory over Dutch leaders, PSV Eindhoven - courtesy of a Lionel Messi hat-trick and a brilliant effort from Ousmane Dembele.
Ernesto Valverde's men continued to charge forward, adding 3 more victories and 1 draw to their name and maintaining an incredible unbeaten record in the tournament after 5 games. The Catalans were also the first side to progress into the knockout rounds, making it look very easy to qualify despite being drawn in a group of death in the Group B.
