Xavi's rejuvenated side enter their Europa League play-off against Manchester United on a stunning, eight-game winning run in all competitions, with their last defeat coming all the way back in October at the hands of Bayern Munich.
This rampant form has opened up an 11-point lead over bitter rivals Real Madrid at the top of La Liga, with Barca also set to face Los Blancos in the Copa del Rey semi-finals after their European double-header with United is out of the way.
