Both sides' recent form has been strong, but with Barcelona having won all of their last five in the Champions League, they should have too much for Benfica.
Over 2.5 goals has occurred in four of Benfica's six games in the Champions League and all of Barcelona's six games in this competition this season, so we should see a pretty high-scoring encounter. All in all, though, it's one Barça should win, given their superiority on paper. Benfica 1-3 Barcelona.
