#3 F.C. Barcelona
Despite the horrors this side has witnessed in the last two seasons of the UEFA Champions League, F.C. Barcelona will enter the group stages with an unrelenting drive.
With Lionel Messi leading the pack from the front, solid introductions of Frenkie De Jong and Antoine Griezmann have added even more proficiency to their first team.
Moreover, the constant speculations of Neymar possibly joining the Catalans very soon is just an icing on the cake. Even though the fans have not been impressed with Valverde's style of play, Barcelona will consider themselves serious contenders to win it all this season.
The Spanish side has enough mastery in their squad to cause mayhem from all fronts this season. The La Liga Champions will be slugging it out with the likes of Borrusia Dortmund, Inter Milan, and Slavia Praha in the group stages of the competition.
Although the initial stages of the competition may test Barca's mettle, the side has enough prowess in their arsenal to get over the line and emerge as the Kings of Europe.
