#1 Barcelona
With the slightest of margins, the team which can be termed as the number one contender is certainly FC Barcelona. With a good 8 point lead in La Liga, they do not face any tough competition back home. Also, the team has match winners like Coutinho, Dembele, Rakitic and Suarez. And well, there is also Messi!
Barcelona should also not be seen as a team which may come under pressure, having won the competition three times in the last 10 years. With serial match winners, Barcelona should go into each match as firm favorites.
Key Players: Lionel Messi (again, stats not required, GOAT?)
Key Positives: Lethal strike force with a lot of creativity, pace down the wing via full-backs, strong campaign, good track record
Key Negatives: None
