I still think Barcelona has a slight advantage maybe 55-60% to win against Manchester United that either 40-45% to win.
I don't think Barcelona will care if they are eliminated by United, they will surely want to win but their focus is on the La Liga, they are top of the La Liga and they just beat real madrid to win the Supercopa, so if they didn't believe before, now they believe that they can win the La Liga from real madrid, and that is the big trophy they want. If the Europa league would be a distraction to them if they go far in it, then it is better they are eliminated by United early. Manchester United have been playing well in the premier league too, but they are not the favorites for it, but in the La Liga barcelona are favorites.
Agree. Simple fact: winning the Europa League while losing La Liga to Real Madrid will be a losing season. Winning La Liga while losing the Europa League at the very early stage (at 1/16 lol) will be a triumph. The priorities are obvious, I even think Xavi would be happy if Barcelona lost to United and he could fully concentrate on La Liga, but of course the circumstances (status) will not allow him to lose this confrontation on purpose.
