At times I think like Xavi Hernandez is trying to play mind games by playing down the chances of his side winning the Europa League and also Manchester United. Barcelona player's returned early enough for training though and some of Manchester United player's also did.
The game will definitely be a hard and beautiful football, Casemiro will unite with one of the old side's he knows and rival's very well.
I'd say the both of them are to score in the game, they're both good attacking and defending side's, expecting a winner at the end will be difficult.
Both are big clubs and have enough quality players even right now Manchester United is facing issues but still have enough power to settle things within team quickly just because of this both are trying to have no hype about this game and results with I have feeling both will try to win and have chance to be into final of the Europa Cup.
Barcelona is surely currently doing amazing stuff with the rank of no 1 in La Liga, and now they will try to have their impact at this league as well because now after second time exit from Champions League is surely having negative about them, and they are surely looking for the better end of this season in both leagues specially after having positive results in domestic league now their next target is European competitions.
