Predictions
Barcelona 2-1 Benfica (SportsMole)
Barcelona boss Xavi is certainly working with a more solid rearguard for this encounter, and the injection of confidence received from assuring themselves of a top-two spot will be invaluable.
Benfica will not be broken down lightly and have fond memories of their September battle with Barca, but we still expect Xavi's reign to continue in perfect fashion here.
