Unleash rested Casemiro against his old rivals and don't let Harry Maguire face Robert Lewandowski: How Man Utd can end Barcelona's incredible eight-game winning streak

Will Barcelona ever lose a game of football again? On current form, it's difficult to say. 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.

After thoroughly underwhelming in continental competitions since taking over at Camp Nou, Xavi will be desperate to get one over on Erik ten Hag over the two legs, but they will have their work cut out to do so.

Like Barca, United are another former European titan that have gone some way to restoring their mythos this season, with Ten Hag already guiding the Red Devils to a domestic cup final and putting them well in contention to finish in the Premier League top four.

United, for their part, have won five of their last six in all competitions, meaning something has to give in Catalunya on Thursday night.
