Man Utd, Arsenal and Juventus are rated as the top 3 candidates for the championship this season.
Man United after defeating Barca, the next opponent is Real Betis. This is not an easy opponent to play when the team from La Liga once overcame AS Roma to top Group C.
With Arsenal, coach Mikel Arteta's army will have to face Sporting Lisbon. With the outstanding quality of personnel, Arsenal is said to not have too many difficulties to win the right to the next round.
Juventus is quite unlucky to meet Freiburg, the representative of the Bundesliga - 1/5 of Europe's top leagues and is also in good form in the Bundesliga this season.
