When two tough teams that are unpredictable meets the game is always interesting. By the end of the game the result will tell which among the both team is the strongest. Manchester United can't afford to losein the game, Ten Hag will make sure his team wins the match.
It's no different from Barcelona, after their failure in the Champions League, coach Xavi will make sure his team wins matches in the Europa League.
This is the right moment with Barcelona's new squad this season
Xavi's toughest challenge is dividing the team's concentration between the Laliga and Europa League competitions
They still have a big chance to win La Liga, as well as in the Europa League
All the teams participating in these two competitions will be in the same situation where they have to divide their concentration, so this shouldn't be the reason why they failed in that competition. I think Xavi Hernandez already knows very well what he has to do to keep his players in good shape. He has experience as a player for sure he himself already understands things like this. Careful preparation and rotation will really help here.
