Alves says Barca, United and Real Madrid are the top three.
"Currently the best teams are us and Manchester United, the last [Champions League] finalists, but Madrid are also competing very well," he told El Mundo Deportivo.
"The Champions League is the most spectacular for what it means, but the league is just as important. our priority is to win the league. It is the competition that is more difficult, the most elaborate. We will try to compete for all."
