Levante is a no march for FC Barcelona in everything the team defeating Barcelona is impossible even if Barcelona is reduced to 9 players they can manage to score a goal but the team will need an added players to be able to defeat the team of Barcelona this season. Against Alaves they didn't just struggle they were not good if they should face Barcelona with that pattern they will concede up to 6 goals in the match.
I see that Flick decided to give Rashford a chance to play in the starting lineup, maybe he trusts him. And also, they said that Rashford plays in Rafinha's position and it will be difficult for him to compete with such a player for a place on the field, but we see that Rafinha is also in the starting lineup and will play in the center, so it turns out that these guys can play together. I think that Barcelona should win easily, and for Rashford this is a big opportunity to show himself, if Flick gives him such a chance, he should take advantage of it.
